New F-contg. quat. ammonium salts of formula R1R2R3R4N)+(RFSO3) - (I) (where RF is perfluorinated 1-12C hydrocarbyl, esp. alkyl, R1 to R4 are opt. same 1-20C alkyl, alkenyl, cycloalkyl or aralkyl gps. and R1, R2 and R3 can form a heterocyclic base with N), are surface active cpds. e.g. for use as wetting agents and tensides, in emulsions, dispersions, cleansers, disinfectants, fire-extinguishers, and as emulsifying assistance in polymerisation. (I) are easily prepd. from perfluorinated sulphonyl fluorides, alkoxy silanes and tert. amines, have wider range of application than alkali perfluoralkyl sulphonates and higher surface tension-reducing activity. |
