摘要
以溴代烷和N,N,N',N'-四甲基乙二胺为原料,经过两步季铵化反应合成了一种新型的不对称型阳离子Gemini表面活性剂——二亚甲基-1-正己基二甲基溴化铵-2-十八烷基二甲基溴化铵(3),其结构经1H NMR和元素分析表征。研究结果表明,3的Krafft点为21.9℃,且聚集能力强。
A novel dissymmetric quaternary ammonium Gemini surfactant,dimethylene-1-hexyldimethyl ammonium bromide-2-octadecyldimethyl ammonium bromide（3）,was synthesized by a two-step quaternization reaction from bromoalkane and N,N,N′,N′-tetramethylethylenediamine.The structures were characterized by 1H NMR and elemental analysis.Krafft of 3 was 21.9 ℃ and cumulated ability was strong.
