以枝杈型含氟醚(4-全氟-[(1,3-二甲基-2-异丙基)-1-丁烯]氧基苯基醚)为原料，通过磺酰化、胺解和季铵化，得到枝杈型含氟季铵盐型阳离子表面活性剂[N-[4-[全氟-(1,3-二甲基-2-异丙基)-1-丁烯]氧基苯磺酰胺基]乙基二乙基甲基碘化铵，其结构经IR、1H-NMR、MS得到确认；其水溶液的临界胶束浓度(CMC)为2.5×10-5 mol×L-1，此时的表面张力为21.0 mN×m-1通过对温度、电解质以及与碳氢表面活性剂的复配研究发现：随着温度的升高其水溶液的CMC和表面张力呈下降趋势；盐度对其影响不大且具有较好的复配性能。

A novel branched fluorinated cationic surfactant diethyl-methyl-(2-{4-[3,4,4,4- tetrafluoro-2-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-1,3-bis-trifluoromethyl-but-1-enyloxy]-benzenesulfonylamino}-ethyl)-ammonium iodide(IV) was synthesized from ((1,1,1,4,5,5,5-heptafluoro-3-(per-fluoropropan-2-yl)-4-(trifluoromethyl)-pent-2-en-2-yl)oxy) benzene via sulphonating with chlorosulfonic acid, ammonolysis with N,N-diethylethylenediamine, methylation with iodomethane. The yield reaches 45 % and the structures were characterized by FT-IR, 1H-NMR and MS. The target compound was evaluated for its surface tension properties, which the surface tension at critical micelle concentration (CMC) 2.5×10-5 mol×L-1 is 21.0 mN×m-1. The effects of temperature, electrolyte and, the combination with hydrocarbon surfactant were investigated. The results indicate that the prepared branched fluorinated cationic surfactant displays good surfactant performance.
