Abstract

The invention relates to N-acyl-aminoalkyl-2-hydroxyethylsulfides of formula R--CONH--(CH.sub.2).sub.n --S--CH.sub.2 --CH.sub.2 --OH, where R is a hydrogen atom or a (C.sub.1 -C.sub.4) alkyl group and n is an integer between 3 and 6, and to a method for preparing them. The method consists in reacting compounds of formula R--CONH--(CH.sub.2).sub.m --CH.dbd.CH.sub.2, where R has the above-mentioned meaning and m is an integer between 1 and 4, with the equivalent quantity of mercaptoethanol at approximately 15.degree. to approximately 150.degree. C. in the presence of a radical starter and in the presence or in the absence of a solvent which is inert to the reactants and to radical reactions.
