titleOfInvention | Process for the preparation of sulphur containing acrylic compounds |
abstract | Process for the preparation of a (meth)acrylate (VI) where G = -CH2SR' (R' = alkyl which may carry an OH functional group, in which case Q = alkyl, or else H); or G = H or CH3, in which case Q = -(CH2)n-SxOyZ (1 </= n </= 12; 1 </= x </= 3; 0 </= y </= 2; and Z = alkyl, cycloalkyl, alkenyl, aryl, alkylaryl, aralkyl or heterocyclic ring which may carry an ester functional group), by reaction of a (meth)acrylate (VII), where R = H, CH3 or -CH2X (X = Hal and Q = alkali metal or alkyl) with a sulphur compound R'SH or ZS(CH2)nX, the said reaction being carried out in an at least partially aqueous medium at 50-100 DEG C or in an organic solvent whose b.p. < 100 DEG C, in the presence of at least one polymerisation inhibitor and of at least one phase transfer agent and resulting, when R = H or CH3, in a (meth)acrylate (VI-a) where G = H or CH3 and y = 0, in which case this first reaction may be followed by an oxidation reaction at approximately 10-60 DEG C, to obtain a (meth)acrylate (VI) where y > 0. <IMAGE> |
