摘要
合成了新型可聚合的单季铵盐阳离子表面活性剂(PMQ)和双季铵盐阳离子表面活性剂(PDQ)。其结构经1HNMR和元素分析表征。在25℃的中性水溶液中PMQ和PDQ的临界胶束浓度分别为25.1mmol·L-1和32.4mmol·L-1,对应的表面张力分别为37.8mN·m-1和40.95mN·m-1。
A novel polymerizable monovalent quaternary ammonium bromide surfactant and the corresponding divalent diquaternary ammonium dibromide surfactant（PDQ） were synthesized. Their structures were characterized by 1H NMR and elemental analysis. The experiment results showed that the critical micelle concentrations of PMQ and PDQ were 25.1 mmol·L^-1 and 32.4 mmol·L^-1 at 25 ℃ in neutral aqueous solution, and the corresponding surface tensions were 37.8 mN·m^-1 and 40.95 mN·m^-1, respectively.
