A process for the synthesis of the fluorochemical compound having formula R.sub.f SO.sub.2 N(CHR.sup.2 --CHR.sup.2 COO.sup.-) R.sup.1 N.sup.+ (R).sub.2 H wherein R.sub.f is a fluoraliphatic radical containing at least 3 carbon atoms. The synthesis involves reaction of compounds of formula R.sub.f SO.sub.2 N(H)R.sup.1 N(R).sub.2 and CHR.sup.2 .dbd.CH.sup.2 COOH in solution at elevated temperatures. The process can be used to synthesize the fluoroaliphatic amphoteric amino carboxylate surfactant having the formula: C.sub.6 F.sub.13 SO.sub.2 N(C.sub.2 H.sub.4 COO.sup.-) C.sub.3 H.sub.6 N.sup.+ (CH.sub.3).sub.2 H which compound is useful in aqueous film-forming foamable concentrates for extinguishing flammable liquid fires.

[FR] Procédé de synthèse du composé fluorochimique de la formule Rf SO2N(CHR2CHR2COO-)R1N+(R)2H dans laquelle Rf représente un radical fluoroaliphatique contenant 3 à 20 atomes de carbone. La synthèse implique la réaction de composés des formules RfSO2N(H)R1N(R)2 et CHR2=CR2COOH en solution, à des températures élevées. Le procédé peut être utilisé dans la synthèse du tensioactif d'amino carboxylate amphotère fluoroaliphatique ayant la formule C6F13SO2N(C2H4COO-)C3H6N+(CH3)2H, ledit composé étant utile dans des concentrés filmogènes pouvant mousser afin d'éteindre des incendies provoqués par des liquides inflammables. [EN] A process for the synthesis of the fluorochemical compound having the formula: Rf?SO2?N(CHR?2-CHR?2COO?-)R?1N?+(R)2?H, wherein Rf? is a fluoraliphatic radical containing 3 to 20 carbon atoms. The synthesis involves reaction of compounds of formula Rf?SO2?N(H)R?1N(R)2? and CHR?2=CR?2COOH in solution at elevated temperatures. The process can be used to synthesize the fluoroaliphatic amphoteric amino carboxylate surfactant having the formula: C6?F13?SO2?N(C2?H4?COO?-)C3?H6?N?+(CH3?)2?H, which compound is useful in aqueous film-forming foamable concentrates for extinguishing flammable liquid fires.
