(57) Abstract This invention relates to lubricants for two-cycle engines comprising a major amount of at least one oil of lubricating viscosity and a minor amount of at least one compound of the general formula AY-MY+ wherein M represents one or more metal ions, y is the total valence of all M and A represents one or more anion containing groups having a total of about y individual anionic moieties and each anion containing group is a group of formula (II).
(Referred to in PCT Gazette No. 06/1994, Section II) i SWO 93/20698 PCT/US93/02541 Title: TWO-CYCLE ENGINE LUBRICANT AND METHOD OF USING
SAME
FIELD OF THE INVENTION This invention relates to lubricant compositions and fuel-lubricant mixtures useful in two-cycle engines.
SMore particularly, it relates to lubricant compositions containing a major amount of an oil of lubricating viscosity and a minor amount of at least one metal carboxylate as described in greater detail hereinbelow.
BACKGROUND OF THE INVENTION Over the past several decades the use of S] spark-ignited two-cycle (2-stroke) internal combustion i !i engines has steadily increased. They are presently found in power lawn mowers and other power-operated garden equipment, power chain saws, pumps, electrical generators, marine outboard engines, snowmobiles, motorcycles and the like. Two-cycle engines have found Ilimited application as automobile and truck engines.
Manufacturers are exploring how to expand this use.
The increasing use of two-cycle engines coupled with increasing severity of the conditions in which they have 4 operated has led to an increased demand for oils to adequately lubricate such engines and which provide enhanced performance. Among the problems associated with two-cycle engines are piston ring sticking, piston scuffing, rusting, lubrication related failure of connecting rod and main bearings and the general formation on the engine’s interior surfaces of carbon and ,WO 93/20698 PCT/US93/02541 -2varnish deposits. Piston ring sticking is a particularly serious problem. Ring sticking leads to failure of the sealing function of piston rings. Such sealing failure causes loss of cylinder compression which is particularly V damaging in two-cycle engines because these engines depend on suction to draw the new fuel charge into the exhausted cylinder. Thus, ring sticking can lead to deterioration in engine performance and unnecessary consumption of fuel and/or lubricant. Other problems associated with two-cycle engines include piston lubricity, scuffing or scoring.
All of the aforementioned problems associated with two-cycle engines must be adequately addressed. Improved performance is continually being sought. The unique problems and techniques associated with the lubrication of two-cycle engines has led to the recognition by those skilled in the art of two-cycle engine lubricants as a distinct lubricant type. See, for example, U.S. Patents 3,085,975; 3,004,837; and 3,753,905.
The compositions of the present invention are effective in controlling the aforementioned problems. While color, per se, is not often a consideration when evaluating performance of a 2-cycle engine lubricant, it may be a consideration for other reasons.
As is well-known, the equipment operator frequently prepares lubricant-fuel blends. A particularly dark colored lubricant or one that imparts a significant color to the lubricant-fuel blend, while not affecting performance, may be deemed to be objectionable.
Furthermore, two-cycle oils frequently contain a small amount of dye, to impart a characteristic color to the lubricant-fuel blend. If the color of the lubricant is pronounced, it may mask the color of the dyed fuel or may I lead the user to believe that the lubricant-fuel blend has deteriorated.
WO 93/20698 PCT/US93/02541 -3- The lubricating compositions of the instant invention are considerably lighter in color than many commercially available lubricants.
U.S. Patent 4,425,138 relates to amino phenols used Sin lubricant fuel mixtures for two-cycle engines. U.S.
Patents 4,663,063 and 4,724,091 issued to Davis relate to a combination of an alkyl phenol and an amino compound in two-cycle engines.

The aromatic group Ar of formula (II) can be a single aromatic nucleus such as a benzene nucleus, a pyridine nucleus, a thiophene nucleus, a 1,2,3,4-tetrahydronaphthalene nucleus, etc., or a polynuclear aromatic moiety. Such polynuclear moieties can be of the fused type; that is, wherein pairs of 2 aromatic nuclei making up the Ar group share two points, 1 such as found in naphthalene, anthracene, the azanaphthalenes, etc. Polynuclear aromatic moieties also can be of the linked type wherein at least two nuclei (either mono or polynuclear) are linked through bridging linkages to each other. Such bridging linkages can be chosen from the group consisting of carbon-to-carbon single bonds between aromatic nuclei, ether linkages, keto linkages, sulfide linkages, polysulfide linkages of 2 to 6 sulfur atoms, sulfinyl linkages sulfonyl linkages, methylene linkages, alkylene linkages, di-(lower alkyl) methylene linkages, lower alkylene ether linkages, alkylene keto linkages, lower alkylene sulfur ‘WO 93/20698 PCT/US93/02541 -8 linkages, lower alkylene polysulfide linkages of 2 to 6 carbon atoms, amino linkages, polyamino linkages and mixtures of such divalent bridging linkages. In certain instances, more than one bridging linkage can be present in Ar between aromatic nuclei. For example, a fluorene nucleus has two benzene nuclei linked by both a methylene linkage and a covalent bond. Such a nucleus may be considered to have 3 nuclei but only two of them are aromatic. Normally, Ar will contain only carbon atoms in the aromatic nuclei per se.

For such reasons as cost, availability, performance, etc., Ar is normally a benzene nucleus, a lower alkylene bridged benzene nucleus, or a naphthalene nucleus. The Group R The compounds of formula employed in the compositions of the present invention preferably contain, directly bonded to at least one aromatic group Ar,\ at least one group R which, independently, is a hydrocarbyl group. More than one hydrocarbyl group can be present, but usually no more than 2 or 3 hydrocarbyl groups are present for each aromatic nucleus in the aromatic group Ar. The number of R groups on each Ar group is indicated by the the subscript m. For the purposes of this invention, each m may be independently 0 or an integer ranging from 1 up to about 10 with the proviso that m does not exceed the unsatisfied valences of the corresponding Ar. Frequently, each m is independently an integer ranging from 1 to about 3. In an especially preferred embodiment each m equals 1. Each R frequently is an aliphatic group containing up to about 750 carbon atoms, frequently from 4 to about 750 carbon atoms, preferably from 4 to about 400 carbon atoms and more preferably from 4 to about 100 carbons. R is preferably alkyl or alkenyl, preferably substantially saturated alkenyl. In one preferred embodiment, R contains at least about 6 carbon atoms, often from 8 to about 100 carbons. In another embodiment, each R contains an average of at least about 30 carbon atoms, often an average of from about 30 to about 100 carbons. In another embodiment, R contains from 12 to about carbon atoms. In a further embodiment, R contains from about 8 to about 24 carbon atoms, preferably from 12 to about 24 carbon atoms and more preferably from 12 to about 18 carbon atoms. In one embodiment, at least one R I~ A WO 93/20698 PCT/US93/02541 -13is derived from an alkane or alkene having number average molecular weight ranging from about 300 to about 800. In another embodiment, R contains an average of at least about 50 carbon atoms. When the group R is an alkyl or alkenyl group having from 2 to about 28 carbon atoms, it is typically derived from the corresponding olefin; for example, a butyl group is derived from butene, an octyl group is derived from octene, etc. When R is a hydrocarbyl group having at least about 30 carbon atoms, it is frequently an aliphatic group made from homo- or interpolymers copolymers, terpolymers) of mono- and di-olefins having 2 to 10 carbon atoms, such as ethylene, propylene, butene-l, isobutene, butadiene, isoprene, 1-hexene, 1-octene, etc. Typically, these olefins are 1-mono olefins such as homopolymers of ethylene. These aliphatic hydrocarbyl groups may also be derived from halogenated chlorinated or brominated) analogs of such homo- or interpolymers. R groups can, however, be derived from other sources, such as monomeric high molecular weight alkenes 1-tetracontene) and chlorinated analogs and hydrochlorinated analogs thereof, aliphatic petroleum fractions, particularly paraffin waxes and cracked and chlorinated analogs and hydrochlorinated analogs thereof, white oils, synthetic alkenes such as those produced by the Ziegler-Natta process poly(ethylene) greases) and other sources known to those skilled in the art. Any unsaturation in the R groups may be reduced or eliminated by hydrogenation according to procedures known in the art. In one preferred embodiment, at least one R is derived from polybutene. In another preferred embodiment, R is derived from polypropylene. In a further preferred embodiment, R is a propylene tetramer. As used herein, the term "hydrocarbyl group" denotes a group having a carbon atom directly attached to the remainder of the molecule and having predominantly 11L WO 93/20698 PCT/US93/02541 14 A Ii hydrocarbon character within the context of this invention. Thus, the term "hydrocarbyl" includes hydrocarbon, as well as substantially hydrocarbon, groups, Substantially hydrocarbon describes groups, including hydrocarbon based groups, which contain non-hydrocarbon substituents, or non-carbon atoms in a ring or chain, which do not alter the predominantly hydrocarbon nature of the group. Hydrocarbyl groups can contain up to three, preferably up to two, more preferably up to one, non-hydrocarbon substituent, or non-carbon heteroatom in a ring or chain, for every ten carbon atoms provided this non-hydrocarbon substituent or non-carbon heteroatom does not significantly alter the predominantly hydrocarbon character of the group. Those skilled in the art will be aware of such heteroatoms, such as oxygen, sulfur and nitrogen, or substituents, which include, for example, hydroxyl, halo (especially chloro and fluoro), alkoxyl, alkyl mercapto, alkyl sulfoxy, etc. Examples of hydrocarbyl groups include, but are not necessarily limited to, the following: hydrocarbon groups, that is, aliphatic alkyl or alkenyl), alicyclic cycloalkyl, cycloalkenyl) groups, aromatic groups phenyl, naphthyl), aromatic-, aliphatic- and alicyclicsubstituted aromatic groups and the like as well as cyclic groups wherein the ring is completed through another portion of the molecule (that is, for example, any two indicated groups may together form an alicyclic radical); substituted hydrocarbon groups, that is, those groups containing non-hydrocarbon containing'substituents which, in the context of this invention, do not significantly alter the predominantly hydrocarbon character; those skilled in the art will be aware of such groups halo (especially chloro and fluoro), WO 93/20698 PCT/US93/02541 hydroxy, alkoxy, mercapto, alkylmercapto, nitro, nitroso, sulfoxy, etc.); hetero groups, that is, groups which will, while having a predominantly hydrocarbon character within the context of this invention, contain atoms other than carbon present in a ring or chain otherwise composed of carbon atoms. Suitable heteroatoms will be apparent to those of ordinary skill in the art and include, for example, sulfur, oxygen, nitrogen. Such groups as, e.g., pyridyl, furyl, thienyl, imidazolyl, etc. are representative of heteroatom containing cyclic groups. Typically, no more than about 2, preferably no more than one, non-hydrocarbon substituent or non-carbon atom in a chain or ring will be present for every ten carbon atoms in the hydrocarbyl group. Usually, however, the hydrocarbyl groups are purely hydrocarbon and contain substantially no such non-hydrocarbon groups, substituents or heteroatoms. Preferably, hydrocarbyl groups R are substantially saturated. By substantially saturated it is meant that the group contains no more than one carbon-to-carbon unsaturated bond, olefinic unsaturation, for every ten carbon-to-carbon bonds present. Usually, they contain no more than one carbon-to-carbon non-aromatic unsaturated bond for every 50 carbon-to-carbon bonds present. In an especially preferred embodiment, the hydrocarbyl group R is substantially free of carbon to carbon unsaturation. It is to be understood that, within the content of this invention, aromatic unsaturation is not normally considered to be olefinic unsaturation. That is, aromatic groups are not considered as having carbon-to-carbon unsaturated bonds. Preferably, hydrocarbyl groups R of the anion containing groups of formula (II) of this invention are substantially aliphatic in nature, that is, they contain no more than one non-aliphatic (cycloalkyl, cycloalkenyl or aromatic) group for every 10 carbon atoms in the R f, *I B WO 93/20698 PCT/US93/02541 -16group. Usually, however, the R groups contain no more than one such non-aliphatic group for every 50 carbon atoms, and in many cases, they contain no such non-aliphatic groups; that is, the typical R group is purely aliphatic. Typically, these purely aliphatic R groups are alkyl or alkenyl groups. Specific non-limiting examples of substantially saturated hydrocarbyl R groups are: methyl, tetra (propylene), nonyl, triisobutyl, oleyl, tetracontanyl, henpentacontanyl, a mixture of poly(ethylene/propylene) groups of about 35 to about 70 carbon atoms, a mixture of the oxidatively or mechanically degraded poly(ethylene/propylene) groups of about 35 to about carbon atoms, a mixture of poly (propylene/l-hexene) groups of about 80 to about 150 carbon atoms, a mixture of poly(isobutene) groups having between 20 and 32 carbon I atoms, and a mixture of poly(isobutene) groups having an average of 50 to 75 carbon atoms. A preferred source of i hydrocarbyl groups R are polybutenes obtained by V polymerization of a C 4 refinery stream having a butene content of 35 to 75 weight percent and isobutene content of 15 to 60 weight percent in the presence of a Lewis acid catalyst such as aluminum trichloride or boron trifluoride. These polybutenes contain predominantly (greater than 80% of total repeating units) isobutene repeating units of the configuration CH CH C 2 1 CH 3 The attachment of a hydrocarbyl group R to the aromatic moiety Ar of the compounds of formula of this invention can be accomplished by a number of techniques well known to those skilled in the art. One particularly suitable technique is the Friedel-Crafts reaction, wherein an olefin a polymer containing an olefinic bond), or halogenated or hydrohalogenated analog thereof, is reacted with a phenol in the presence 'WO 93/20698 PCT/US93/02541 -17 of a Lewis acid catalyst. Methods and conditions for carrying out such reactions are well known to those skilled in the art. See, for example, the discussion in the article entitled, "Alkylation of Phenols" in "Xirk-Othmer Encyclopedia of Chemical Technology", Third Edition, Vol. 2, pages 65-66, Interscience Publishers, a division of John Wiley and Company, and U.S. Patents 4,379,065; 4,663,063; and 4,708,809, all of which are expressly incorporated herein by reference for relevant disclosures regarding alkylation of aromatic compounds. Other equally appropriate and convenient techniques for attaching the hydrocarbon-based group R to the aromatic moiety Ar will occur readily to those skilled in the art. The Groups Z Each Z is independently OH, (OR )bOH or 0 wherein 4 each R is independently a divalent hydrocarbyl group and b is a number ranging from 1 to about The subscript c indicates the number of Z groups that may be present as substituents on each Ar group. There will be at least one Z group substituent, and there i may be more, depending on the value of the subscript m. ~I For the purposes of this invention, c is a number ranging from 1 to about 3. In a preferred embodiment, c is 1. As will be appreciated from the foregoing, the compounds of Formula I employed in this invention contain at least two Z groups and may contain one or more R groups as defined hereinabove. Each of the foregoing groups must be attached to a carbon atom which is a part of an aromatic nucleus in the Ar group. They need not, however, each be attached to the same aromatic nucleus if more than one aromatic nucleus is present in the Ar group. As mentioned hereinabove, each Z group may be, independently, OH, 0 or (OR )bOH as defined hereinabove. In a preferred embodiment, each Z is OH. In another embodiment, each Z may be 0 In another WO 93/20698 PCT/US93/02541 -18 preferred embodiment, at least one Z is OH and at least one Z is Alternatively, at least one Z may be a 4 group of the Formula (OR )bOH. As mentioned hereinabove, each R is independently a divalent hydrocarbyl group. Preferably, R 4 is an aromatic or an aliphatic divalent hydrocarbyl group. Most preferably, R 4 is an alkylene group containing from 2 to about 30 carbon atoms, more Ii preferably from 2 to about 8 carbon atoms and most preferably 2 or 3 carbon atoms. The subscript b typically ranges from 1 to about preferably from 1 to about 10, and most preferably 1 or 2 to about The Groups R 1 R 2 ad R 3 1 2 3 Each of the groups R, R 2 and R is independently H or a hydrocarbyl group. In one embodiment, each of R, R and R is, independently, H or a hydrocarbyl group I having from 1 to about 100 carbon atoms, more often from S1 to about 24 carbon atoms. In a preferred embodiment, each of the aforementioned groups is independently hydrogen or alkyl or an alkenyl group. In one preferred embodiment each of R R and R is, independently, H or lower alkyl. In an especially preferred embodiment, each of the aforementioned groups is H. For the purposes of this invention, the term "lover" when used to describe an alkyl or alkenyl group means from 1 to 7 carbon atoms. The subscript x denotes the number of R 2 -C- 13 R groups present in the anion containing group of Formula SII. For the purposes of this invention, x normally ranges from 0 to about 8. In a preferred embodiment, x is 0, 1 or 2. Most preferably x equals 0. The Group T It will be apparent that when t 1 in any of Formula II, V or VI, that groups of Formulae V or VI will be present. Termination takes place when t 0. Thus, *WO 93/20698 PCT/US93/0254 19 for example, when t 1 on Formula II, a group of Formula V or VI will be present. It follows then that in order for a group of Formula V or VI to be present in the anion containing group of Formula II, t in Formula II equals 1. Likewise when t 1 in Formula II a group of Formula V or VI is present. When t in either Formula V or VI eqvals 0, no further T groups are present. However, when t in Formula V or VI equals 1, one or more additional T groups are present, terminating only when finally t 0. In one preferred embodiment t in Formula II equals 0 I and no groups of Formula V or VI are present. In another Spreferred embodiment t in Formula II equals 1 and from 1 to about 3, preferably up to 2 additional groups T of Formula V or VI are present. The Metal Ions M The symbol M in Formula I represents one or more metal ions. These include alkali metal, alkaline earth metals, zinc, cadmium, lead, cobalt, nickel, iron, manganese, copper and others. Preferred are the alkali and' alkaline earth metals. Especially preferred are sodium, potassium, calcium, and lithium. Most preferred are sodium and lithium. The metal ions M may be derived from reactive metals or reactive metal compounds that will react with carboxylic acids or phenols to form carboxylates and phenates. The metal salts may be prepared from reactive metals such as alkali metals, alkaline earth metals, zinc, lead, cobalt, nickel, iron and the like. Examples of reactive metal compounds are sodium oxide, sodium hydroxide, sodium carbonate, sodium methylate, sodium phenoxide, corresponding potassium and lithium compounds, calcitm oxide, calcium hydroxide, calcium carbonate, calcium methylate, calcium chloride, calcium phenoxide, and corresponding barium and magnesium compounds, zinc oxide, zinc hydroxide, zinc carbonate, cadmium chloride, lead oxide, lead hydroxide, lead carbcnate, nickel oxide, nicke) hydroxide, nickel nitrate, cobalt oxide, ferrous I- i WO 93/20698 PCTUS93/02541 20 carbonate, ferrous oxide, cupric acetate, cupric nitrate, etc. The above metal compounds are merely illustrative of those useful in this invention and the invention is not to be considered as limited to such. Suitable metals and metal-containing reactants are disclosed in many U.S. Patents including U.S. Patent Numbers 3,306,908; 3,271,310; and U.S. Reissue Patent Number 26,433. The Total Valence V The skilled worker will appreciate that the compounds of the general formula AY-M y (I) constitute a substantially neutral metal salt, which metal salt is a carboxylate and/or phenate, depending on the nature of A. Depending on the nature of the group Z in Formula (II) A may be a carboxylate, or a carboxylate-phenate, a carboxylate-mixed phenate/phenol, a carboxylate-alkoxylate, a carboxylate-phenatealkoxylate, a carboxylate-phenate/phenol-alkoxylate, etc. The group A may also represent mixtures of two or more of these. Accordingly, it is apparent that the value of y is dependent upon the number of anion-containing moieties making up A and on the valence of the metal ion M. Preferably, salts of Formula I are neutral salts. However, it is to be understood that salts of formula I comprising up to about 50% unreacted carboxylic acid groups or lactone are also contemplated as being within the scope of this invention.

When R is H, the aldehyde moiety of reactant (IV) may be hydrated. For example, glyoxylic acid is readily available commercially as the hydrate having the formula (HO)2CH-COOH. Water of hydration as well as any water generated by the condensation reaction is preferably removed during the course of the reaction. Ranges of values and descriptions of the groups and subscripts appearing in the above Formulae (III) and (IV) are the same as recited hereinabove for Formulae and When R is an alkyl group it is preferably a lower alkyl group, most preferably, ethyl or methyl.

The intermediate arising from the reaction of (a) and may be a carboxylic acid or a lactone, depending upon the nature of In particular, when is a highly hindered hydroxy aromatic compound, the product from and is usually a carboxylic acid. When the hydroxy aromatic reactant is less hindered, a lactone is generated. Often, the intermediate arising from the reaction of and is a mixture comprising both lactone and carboxylic acid. When the intermediate from and is further reacted with the metal-containing reactant, generally a Scarboxylic acid salt is formed first. If an excess of metal reactant is used, an amount beyond that needed for formation of a carboxylic acid salt, further reaction takes place at aromatic -OH groups. From time to time it has been noted that before all lactone is converted to carboxylic acid salt, the WO 93/20698 PCT/US93/02541 beginning of conversion of phenolic -OH groups to 0 groups, phenate salts, is observed. This appears to occur most often when the metal reactant is a calcium reactant. The carboxylate salt forms by reaction of the metal containing raactant with the lactone, opening the lactone ring, forming a carboxylate salt, or from direct reaction with a carboxylic acid group. It is generally preferred to utilize sufficient metal-containing reactant to substantially neutralize all of the carboxylic acid; however, conversion of at least 50%, more preferably of lactone or carboxylic acid to carboxylic acid salt is desirable. Preferably, at least 90%, more preferably 99-100% conversion of lactone or carboxylic acid to Scarboxylic acid salt is effected. IThe following specific illustrative Examples describe the preparation of the compounds of Formula (I) useful in the compositions of this invention. In the following examples, as well as in the claims and in the specification of this application, parts are parts by weight, the temperature is degrees Celsius and the pressure is atmospheric, unless otherwise indicated. As will be readily apparent to those skilled in the art, variations of each of the illustrated reactants and combinations of reactants and conditions may be used.

The product contains, by analysis, 1.16% Na and has a total base number of 27.2. In addition to the metal salts of Formula I the use of other additives is contemplated. It is sometimes useful to incorporate, on an optional, as-needed basis, other known additives which include, but are not limited to, dispersants and detergents of the ash-producing or ashless type, antioxidants, anti-wear agents, extreme pressure agents, emulsifiers, demulsifiers, foam inhibitors, friction modifiers, anti-rust agents, corrosion inhibitors, viscosity improvers, pour point depressants, dyes, lubricity agents, and solvents to i'prove handleability which may include alkyl and/or ary hydrocarbons. These optional additives may be present in various amounts depending on the intended application for the final product or may be excluded therefrom. The ash-containing detergents are the well-known neutral or basic Newtonian or non-Newtonian, basic salts of alkali, alkaline earth and transition metals with one or more hydrocarbyl sulfonic acid, carboxylic acid, phosphoric acid, mono- and/or dithio phosphoric acid, phenol or sulfur coupled phenol, and phosphinic and thiophosphinic acid. Commonly used metals are sodium, potassium, calcium, magnesium, lithium, copper and the like. Sodium and calcium are most commonly used. Neutral salts contain substantially equivalent amounts of metal and acid. As uwed herein, the expression basic salts refers to those compositions containing an excess amount of metal over that normally As WO 93/20698 PCT/US93/02541 38 required to neutralize the acid substrate. Such basic compounds are frequently referred to as overbased, superbased, etc. Dispersants include, but are not limited to, hydrocarbon substituted succinimides, succinamides, carboxylic esters, Mannich dispersants and mixtures thereof as well as materials functioning both as dispersants and viscosity improvers. The dispersants include nitrogen-containing carboxylic dispersants, ester dispersants, Mannich dispersants or mixtures thereof. Nitrogen-containing carboxylic dispersants are prepared by reacting a hydrocarbyl carboxylic acylating agent (usually a hydrocarbyl substituted succinic anhydride) with an amine (usually a polyamine). Ester dispersants are prepared by reacting a polyhydroxy compound with a hydrocarbyl carboxylic acylating agent. The ester dispersant may be further treated with an amine. Mannich dispersants are prepared by reacting a hydroxy aromatic compound with an amine and aldehyde. The dispersants listed above may be post-treated with reagents such as urea, thiourea, carbon disulfide, aldehydes, ketones, carboxylic acids, hydrocarbon substituted succinic anhydride, nitriles, epoxides, boron compounds, phosphorus compounds and the like. These dispersants are generally referred to as ashless dispersants even though they may contain elements such as boron or phosphorus which, on decomposition, will leave a non-metallic residue. Extreme pressure agents and corrosion- and oxidation-inhibiting agents include chlorinated compounds, sulfurized compounds, phosphorus containing compounds including, but not limited to, phosphosulfurized hydrocarbons and phosphorus esters, metal containing compounds and boron containing compounds. Chlorinated compounds are exemplified by chlorinated aliphatic hydrocarbons such as chlorinated wax. W f I 11 tI U Ii ii WO 93/20698 PCT/US93/0254I 39 Examples of sulfurized compounds are organic sulfides and polysulfides such as benzyl disulfide, bis(chlorobenzyl)disulfide, dibutyl tetrasulfide, sulfurized methyl ester of oleic acid, sulfurized alkylphenol, sulfurized dipentene, and sulfurized terpene. Phosphosulfurized hydrocarbons include the reaction product of a phosphorus sulfide with turpentine or methyl oleate. Phosphorus esters include dihydrocarbon and trihydrocarbon phosphites, phosphates and metal and amine salts thereof. Phosphites may be represented by the following formulae: 0 II R 5 0-P-OR H (R 5 0) 3 P wherein each R 5 is independently hydrogen or a hydrocarbon based group, provided at least one R 5 is a hydrocarbon based group. Phosphate esters include mono-, di- and trihydrocarbon-based phosphates of the general formula j: (R Examples include monotriaryl and mixed alky: Metal containii thiocarbamates, such a barium heptylphenyl compounds. Boron containing boron-nitrogen conta: 50) PO.

Viscosity improvers include, but are not limited to, polyisobutenes, polymethacrylate acid esters, polyacrylate acid esters, diene polymers, polyalkyl styrenes, alkenyl aryl conjugated diene copolymers, polyolefins and multifunctional viscosity improvers. Pour point depressants are a particularly useful type of additive often included in the lubricating oils described herein. See for example, page 8 of "Lubricant Additives" by C. V. Smalheer and R. Kennedy Smith (Lesius-Hiles Company Publishers, Cleveland, Ohio, 1967). Lubricity agents include synthetic polymers polyisobutene having a number average molecular weight in the range of about 750 to about 15,000, as measured by vapor phase osmometry or gel permeation chromatography), polyolether poly (oxyethylene-oxypropylene ethers) and ester oils. Natural oil fractions such as bright stocks (the relatively viscous products formed during conventional lubricating oil manufacture from petroleum) can also be used for this purpose. They are usually present, when used in two-cycle oils in amounts of about 3% to about 20% by weight of the total composition. Diluents include such materials as petroleum naphthas boiling in the range of 30° to about 90"C Stoddard Solvent). When used, they are typically present in amounts ranging from about 5% to about 25% by weight. Anti-foam agents used to reduce or prevent the formation of stable foam include silicones or organic polymers. Examples of these and additional anti-foam compositions are described in "Foam Control Agents", by Henry T. Kerner (Noyes Data Corporation, 1976), pages 125-162. These and other additives are described in greater detail in U.S. Patent 4,582,618 (column 14, line 52 through column 17, line 16, inclusive), herein incorporated by reference for its disclosure of other -i: i 11 -WO 93/20698 PCT/US93/02541 41 additives that may be used in the compositions of the present invention. The components may be blended together in any suitable manner and then admixed, for example with a diluent to form a concentrate as discussed below, or with a lubricating oil, as discussed below. Alternatively, components can be admixed separately with such diluent or lubricating oil. The blending technique for mixing the components is not critical and can be effected using any standard technique, depending upon the specific nature of the materials employed. In general, blending can be accomplished at room temperature; however, blending can be facilitated by heating the components. As previously indicated, the compositions of the present invention are useful as additives for lubricants for 2-cycle engines. They can be employed in a variety of lubricant basestocks comprising diverse oils of lubricating viscosity, including natural and synthetic lubricating oils and mixtures thereof. Natural oils include animal oils, vegetable oils, mineral lubricating oils, solvent or acid treated mineral oils, and oils derived from coal or shale. Synthetic lubricating oils include hydrocarbon oils, halo-substituted hydrocarbon oils, alkylene oxide polymers, esters of carboxylic acids and polyols, esters of polycarboxylic acids and alcohols, esters of phosphorus-containing acids, polymeric tetrahydrofurans, silicon-based oils and mixtures thereof. Specific examples of oils of lubricating viscosity are described in U.S. Patent 4,326,972 and European Patent Publication 107,282, both herein incorporated by reference for their disclosures relating to lubricating oils. A basic, brief description of lubricant base oils appears in an article by D. V. Brock, "Lubricant Base Oils", Lubrication EngineerinQ, volume 43, pages 184-185, March, 1987. This article is herein incorporated by reference for its disclosures relating to lubricating mom 4 WO 93/20698 PCF/US93/02541 -42oils. A description of oils of lubricating viscosity occurs in U.S. Patent 4,582,618 (column 2, line 37 through column 3, line 63, inclusive), herein incorporated by reference for its disclosure to oils of lubricating viscosity. The additives and components of this invention can be added directly to the lubricant. Preferably, however, they are diluted with a substantially inert, normally liquid organic diluent such as mineral oil, naphtha, toluene or xylene, to form an additive concentrate. These concentrates usually contain from about 10% to about 90% by weight of the components used in the composition of this invention and may contain, in addition, one or more other additives known in the art as I described hereinabove. The remainder of the concentrate is the substantially inert normally liquid diluent. The following Examples illustrate additive concentrates useful for preparing two-cycle lubricating oil compositions. All percentages are by weight. Totals may not add up to 100% because of rounding. iiEXAMPLE I An additive concentrate for two-cycle engine lubricants contains 2.55% of basic calcium sulfonate, 0.91% overbased, carbonated calcium sulfonate, 0.60% poly (propoxy-ethoxy) alcohol, 90.6% of the product of Example I and 0.30% of alkylated diphenylamine. EXAMPLE II An additive concentrate for two-cycle engine lubricants contains 8.45% of basic calcium sulfonate, 1.01% overbased, carbonated calcium sulfonate, 0.68% poly (propoxy-ethoxy) alcohol, 72.6% of the product of example I, 16.89% of basic methylene-coupled calcium alkyl phenate and 0.34% of alkylated diphenyl amine. As is well known to those skilled in the :rt, two-cycle engine lubricating oils are often added directly to the fuel to form a mixture of a lubricant and fuel which is then introduced into the engine cylinder. 'WO 93/20698 PCT/US93/02541 43 Such lubricant-fuel mixtures are within the scope of this invention. Such lubricant-fuel mixtures generally contain a major amount of fuel and a minor amount of lubricant, more often at least about 10, preferably about more preferably about 20 up to about 100, more preferably up to about 50 parts of fuel per 1 part of lubricant. The fuels used in two-cycle engines are well known to those skilled in the art and usually contain a major portion of a normally liquid fuel such as hydrocarbonaceous petroleum distillate fuel motor gasoline as defined by ASTM Specification D-439-73). Such fuels can also contain non-hydrocarbonaceous materials such as alcohols, ether, organo-nitro compounds and the like methanol, ethanol, diethyl ether, I methyl ethyl ether, nitromethane) are also within the scope of this invention as are liquid fuels derived from vegetable or mineral sources such as corn, alfalfa, shale Sand coal. Mixtures of fuels, such as mixtures of gasoline and alcohol, for example, methanol or ethanol are among the useful fuels. Examples of fuel mixtures are combinations of gasoline and ethanol, diesel fuel and ether, gasoline and nitromethane, etc. Particularly preferred is gasoline, that is, a mixture of hydrocarbons having an ASTM boiling point of 60"C. at the 10% distillation point to about 205*C. at the 90% distillation point. Natural gas is also useful as a fuel for two-cycle engines. Two-cycle fuels also contain other additives which f7 are well known to those of skill in the art. These may include ethers, such as ethyl-t-butyl ether, methyl-t-butyl ether and the like, alcohols such as ethanol and methanol, lead scavengers such as halo-alkanes ethylene dichloride and ethylene dibromide), dyes, cetane improvers, antioxidants such as 2,6 di-tertiary-butyl-4-methylphenol, rust inhibitors, 'WO 93/20698 PCT/US93/02541 44 such as alkylated succinic acids and anhydrides, bacteriostatic agents, gum inhibitors, metal deactivators, demulsifiers, upper cylinder lubricants, anti-icing agents and the like. The invention is useful with lead-free as well as lead-containing fuels. Two cycle engine lubricating oils of this invention are illustrated in the following examples. All parts and percentages are by weight and unless indicated otherwise, amounts of components are given on a diluent-free basis. Amounts of components from the preceding Examples are given as prepared and are not adjusted for oil content. ii I i i W TABLE ill0' Each of the lubricating oil compositions in this table contains 0.04% of poly (propoxy-ethoxy) alcohol,0.21 of a methyllene-coupled aljcylated naphthalene as described in U.S. Patent 4,753,745, 0.25t of a basic calcium sulfonate, 0.035% of an overbased, carbonated calcium sulfonate and 15% of a hydrocarbon solvent(Stoddard Solvent-Defined In )ASTM D-484-52), an amount of a component as given In the table and two-cycle mineral oil basestock sufficient to make the total composition l00t 1 4 6 2 J6I 13 j6I 14 j6 3 16 6 j6 2 3 4 9 I41 I 9 J 2I 36 4 4 I2 J9 21 I 'WO 93/20698 PCT/US93/02541 46 Example U A chain saw lubricating oil is made up of 0.22% of a polymer of alkyl fumarate, vinyl acetate and vinyl ethyl ether, 8% Stoddard Solvent, 0.25% of basic calcium sulfonate, 0.024% of overbased carbonated calcium sulfonate, 0.04% of poly (propoxy-ethoxy) alcohol, 0.017% of alkylated diphenyl amine, 4.3% of the product of Example 2 and sufficient mineral oil basestock comprising 88% 600 neutral oil and 12% 150 Bright Stock to bring the total up to 100%.

As mentioned hereinabove, this invention also relates to methods for lubricating two-cycle engines. In i one embodiment, a lubricant for two-cycle engines of this Sinvention is added to a fuel and the engine is operated employing this lubricant-fuel mixture as the operating fuel. i With many engines, particularly larger engines, the fuel and lubricant are supplied separately to the engine. The lubricant may be supplied to the fuel intake system either before or after the carburetor and before the fuel is drawn into the combustion chamber. At least some mixing of the lubricant and fuel takes place under these conditions. I In another embodiment, a lubricant of this invention is supplied to the operating engine separately from the fuel. This may be accomplished by injecting lubricant 41 into the crankcase, then some of the lubricant is drawn into the combustion chamber. Fuel is generally injected directly into the combustion chamber. In both cases, the lubricant is consumed during combustion and a fresh lubricant is supplied with each fuel charge. 'WO 93/20698 PCTUS9302541 48 Two-cyc.a lubricating oil compositions were evaluated employing the Yamaha Y-350 M2 Test Procedure. The test engine is a 347 cm 3 Yamaha RD-350B twin-cylinder air-cooled motorcycle engine. The test is primarily designed to evaluate ring-sticking and piston skirt deposits. 0'park plug fouling, combustion chamber deposits and exhaust port blockage are also evaluated. A separate oil is evaluated in each cylinder allowing a direct comparison of a test oil with a otandard, i.e., reference oil. Typically, fuel:oil ratio is about 50:1 although this may be varied. The test procedure involves a 25 minute 6000 rpm (revolutions per minute), horsepower cycle and a 5 minute idle cycle repeated five times with a 60 minute minimum shutdown after each 150 minutes of running time, then repeating until 20 hours running time is completed. Another test to evaluate piston skirt varnish and ring sticking performance of two-cycle engine lubricants is the West Bend 10 Hour Deposit Test. The test engine is a gasoline fueled, single cylinder, 134 cm 3 air-cooled utility two-cycle engine. The engine is operated employing the test lubricant at 50:1 fuel:oil ratio for hours at 5000 rpm, 4.7 horsepower. Numerical ratings are assigned for piston skirt varnish, ring sticking, exhaust port blockage and piston undercrown deposits, Lubricating oil compositions of this invention when evaluated on the above tests generally provide performance at least comparable to commercially available two-cycle lubricants and often exceed the performance of these commercial oils. While the invention has been explained in relation to its preferred embodiments, it is to be understood that i various modifications thereof will become apparent to those skilled in the art upon reading the specification. Therefore, it is to be understood that the invention disclosed herein is intended to cover such modifications as fall within the scope of the appended claims. i,' Claims (15) 4-9 'WO 93/20698 PCTIUS93/02541 AMENDED CLAIMS [received by the International Bureau on 9 September 1993 (09.09.93) original claims 1-83 replaced by amended claims 1-25 (9 pages)] 1.
