Abstract of the Disclosure The invention is directed to fluorinated alkylamidoalkane sulfonic acids and salts of the formula Image , wherein Rf is straight or branched chain perfluoroalkyl of 1 to 18 carbon atoms or perfluoroalkyl substituted by perfluoroalkoxy of 2 to 6 carbon atoms, R1 is hydrogen or lower alkyl and R2, R4 and R5 are independently hydrogen or alkyl, and R6 is alkylene, alkylenethioalkylene, alkyleneoxyalkylene or alkylene- iminoalkylene with a secondary or tertiary nitrogen atom. R3 is hydrogen, alkyl, aryl or pyridyl, M is hydrogen, an alkali metal, an alkaline earth metal, a group derived from an organic base or ammonium, and n is an integer corresponding to the valency of M. Said compounds are prepared by a base catalyzed additon reaction of the thiol, Rf-R6SH, to an alkenylamidoalkane sulfonic acid salt. She compounds are useful as surfactants and as levelling agents in floor polish formulations.
