    Abstract: 1346644 Fluoroalkyl sulphonamides FARBWERKE HOECHST AG 14 April 1971 [19 March 1970] 24521/71 Heading C2C [Also in Division C5] Compounds of formula wherein R f is a C 4-10 perfluoroalkyl group, n is 2 or more, m is 2 to 6, R 1 and R 11 are C 1-4 alkyl, R 111 is hydrogen, C 1-4 alkyl or an aralkyl group having 1 or 2 carbon atoms in the alkylene moiety, X is an anion and A is a C 1-4 alkylene group, are prepared by reaction of a sulphonyl halide of formula R f (CH 2 ) n SO 2 Cl with a diamine of formula NH 2 (CH 2 ) m NR 1 R 11 , followed if desired by salt formation. The betaines are obtained by reaction with a halocarboxylic acid, or an alkali or alkaline earth metal salt thereof, or with a lactone. The products are surface active or inter-face active agents, in particular wetting, foaming, emulsifying and dispersing agents, and may be used in dry-cleaning compositions.
