Abstract

1511773 Piperidyl – triazine derivatives CHIMOSA CHIMICA ORGANICA SpA 29 June 1976 [18 Dec 1975] 27110/76 Heading C2C [Also in Division C3] Novel piperidyl-triazine derivatives of the formula wherein R 1 and R 2 are the same or different and each is hydrogen, hydroxyl, straight or branched chain C 1 to C 18 alkyl, C 5 to C 18 cyoloalkyl, substituted or unsubstituted C 6 to C 18 aryl, C 7 to C 18 aralkyl, a piperidine radical of Formula (II) in which R 4 , R 5 , R 7 and R 8 are the same or different and each is C 1 to C 6 alkyl and R 6 is H, -O, C 1 to C 12 alkyl, or C 2 to C 12 alkenyl or alkynyl, or R 1 and R 2 may be in which R 9 and R 10 are the same or different and each is hydrogen, C 1 to C 8 alkyl, C 5 to C 8 cycloalkyl, or C 6 to C 8 aryl; X and Y are the same of different and each is -O-, -S-, or R 11 being H, straight or branched chain C 1 to C 18 alkyl, C 5 to C 18 cycloalkyl, C 6 to C 18 aryl, C 7 to C 18 aralkyl or a piperidine radical of Formula (II); R 1 -X- and R 2 -Y-, taken as a single substitutent group, may be a radical of a nitrogenous heterocyclic compound having 5 to 8 ring atoms linked to the triazine ring by means of a disubstituted nitrogen atom of said radical, or R 1 -X- and R 2 -Y- may be Cl- or Br-; n is an integer from 2 to 6; R 3 is an n-valent residue derived from a polyalcohol, a polymercaptan or a polyamino by reaction of the active H atoms thereof with a halogen atom of a monohalo triazine; or R 3 may be R 12 -(Z)- n , where R 12 is an n-valent C 1 to C 18 aliphatic, C 5 to C 18 cycloaliphatic or C 6 to C 18 aromatic radical, and Z is -O-, -S- or R 11 being as defined above; n=2, radical R 3 may be a divalent radical of a nitrogenous heterocyclic compound having 6-8 ring atoms, the disubstituted nitrogen atoms of which are linked to a triazine ring; when n = 2, radical R 3 may be in which R 13 and R 14 are the same or different, and each is hydrogen, C 1 to C 12 alkyl, C 5 to C 12 cycloalkyl, C 6 to C 12 aryl, C 7 to C 12 aralkyl, or a piperidine radical of Formula (II); when n = 3 4, 5, or 6, R 3 may be wherein R 11 is as defined above, r and s are the same or different and each is an integer from 2 to 6, and t is 0,1,2 or 3 provided that at least one piperidine radical of Formula (II) is present in at least one of the radicals R 1 -X-, R 2 -Y-, and R 3 , are prepared by reacting a 4,6-disubstituted-2-halotrizine or a 6-substituted- 2,4-dihalotriazine with the appropriate polyalcohol, polymercaptan or polyamine in an inert solvent at elevated temperature and in the presence of an organic or inorganic base. The novel compounds may be used as light stabilizers for organic polymers. The triazine starting material may be prepared by reacting cyanuric chloride with an appropriate amine.
