Abstract
A process for the preparation of condensation products of thioglycolic acid or its esters with olefins having the general formula: ** (See formula) ** wherein R means a branched hydrocarbon chain and R 'a hydrogen or an alcohol radical, and more especially the tetrapropylene derivatives ** (See formula) ** and the tripropylene derivatives ** (See formula) ** in which R 'has the aforementioned significance and especially the S- (1,3,5,7-tetramethyl octyl) mercaptoacetatic acid and its esters and more especially the butyl ester and the S- (1, 3,5-trimethyl) acid hexyl) mercaptoacetic acid and its esters, and more especially the butyl ester, characterized in that the thioglycolic acid or an alkyl thioglycolate is reacted on an olefin in the presence of a Friedel-Crafts reaction catalyst, the catalyst is removed, washed with water or with a dilute acid, and the product of the reaction of the raw materials that have not reacted is distilled, by vacuum distillation or by steam stripping.
