Process for the preparation of non-ionic surface-active agents from isopropylidene-1,2 epoxypropyl-3 glycerol and from a mercaptan, surface-active products and use of same.

摘要

Process for the preparation of nonionic surface-active products by reaction of a compound containing a mercaptan functional group with 1,2-isopropylidene-3-epoxypropylglycerol according to the reaction: <IMAGE> followed by hydrolysis and optional oxidation to sulphoxide to obtain the compound <IMAGE> R denotes a C8-C36 aliphatic, cycloaliphatic or alkylaryl radical, n denotes a whole or decimal number from 1 to 10, w is equal to 0 or 1.
