ABSTRACT:
The invention is directed to alkylthio alkylamido sulfonic acids and salts of the formula ##STR1## R.sub.6 is unsubstituted or substituted alkyl, cycloalkyl or phenyl, alkylthio, tert-alkylamine, furfuryl or a group derived from a polyfunctional mercaptan, R.sub.1 is hydrogen or lower alkyl and each of R.sub.2, R.sub.4 and R.sub.5 is individually hydrogen or a hydrocarbon radical. R.sub.3 is hydrogen, alkyl, aryl or pyridyl, M is hydrogen, a monovalent alkali metal, an alkaline earth metal, an organic base or ammonium, and n is an integer corresponding to the valency of M. Said compounds are prepared by a base catalyzed addition reaction of a reactive mercaptan to an alkylenylamidoalkane sulfonic acid salt. The compounds are useful as surfactants.
