Abstract

1447669 Catalyst composition ROHM & HAAS CO 13 Sept 1973 [6 Oct 1972] 43136/73 Heading B1E [Also in Division C2] A catalyst composition, used in the reaction of formaldhyde with an alkanoic acid or ester or an alkyl nitrile to give unsaturated compounds, comprises pyrogenic silica, optionally admixed with up to 10% wt of pyrogenic zirconia, the silica having a total surface area of from 150-300 m2/g, a total pore volume of 3-15 cc/g and a pore size distribution such that at least 50% of the pore content is constituted by pores having a diameter in excess of 10000Š, less that 30% by pores of diameter less than 1000Š and the remaining pore content by pores in the range 1000-10000Š, the silica having been calcined with a base activating agent which increases the basicity of the silica. The base activating agent may be organic, e.g. pyridines, alkylamines, quaternary ammonium salts, alkali metal salts of carboxylic acids or sulphur-containing organic bases such as trimethyl sulphonium hydroxide, or it may be inorganic, e.g. metals of Gps IA, IIA and IIIB and their salts, oxides, superoxides, hydroxides or amides. Other specified activating agents include antimony pentoxide; borax; sodium phosphate, hydrogen phosphate, carbonate, silicate and tungstate; ferrous hydroxide; cesium molybdate; stannic oxide; and magnesium aluminium silicate. The Examples relate to catalysts wherein the base acitvating agent used is potassium hydroxide, cesium hydroxide and/or cesium stearate (buffered by disodium hydrogen phosphate and borax), substituted hydroxylamines or sodium pyrophosphate.
