| 摘 要： | 以全氟丁基磺酰氟与N，N’-二甲基-1，3-丙二胺为原料，合成全氟丁基磺酰胺，再与烷基二溴季铵盐化，首次成功得到了4种全氟丁基型阳离子表面活性剂，并通过19^FNMR、1^HNMR、MS和IR进行表征；结：果表明，该2-N-[3-（二甲基氨）-丙基]全氟丁基磺酰胺二溴丙烷季铵盐表面活性剂在25℃时的表面张力为21．25mN／m，临界胶束浓度为0．002g／L，表现出较高的表面活性。

| Abstract: | A series of novel perfluorobutyl-type cationic surfactant have been successfully synthesized for the first time,employing perfluorobutyl sulfonyl fluoride and N,N-dimethylpropane-1,3-dimine as raw materials to produce perfluorobutyl sulfonylurea amide firstly,and followed by reacting with alkyl dibromide.The as-prepared surfactants have been characterized by 19F NMR,1H NMR,MS and IR.By comparison,perfluorobutyl cationic surfactant with three alkyl chains demonstrates the highest activity with surface tension of the 21.25 mN/m under 25 ℃,and critical micelle concentration of 0.002 g/L. |
