Abstract
Preparation of acyltaurides of the general formula R -- CO -- NH -- CH.sub.2 -- CH.sub.2 -- SO.sub.3 M wherein R denotes a C.sub.7 --C.sub.21 --alkyl or --alkenyl radical, which can be substituted by one or two hydroxyl groups, and M denotes an alkali metal or alkaline earth metal cation, ammonium or mono-, di- or tri-alkanolammonium, by reacting the corresponding fatty acids or their mixtures, urea and alkali metal hydroxyethanesulphonates or alkaline earth hydroxyethanesulphonates and, optionally by converting the reaction products into the ammonium or mono-, di- or tri-alkanolammonium salts.
