摘要
以二乙胺、二氯乙烷和溴代十二烷为原料,根据胺的烷基化原理,通过两步法合成了双(二乙基十二烷)乙撑双季铵盐 Gemini 表面活性剂。对合成产物进行了红外光谱分析,其结构与预期结构相符。测定了其水溶液的表面张力及临界胶束浓度,结果表明其具有较高的表面活性。
Bis（diethyl lauryl） ethylene double quaternary ammonium salt surfactant was synthesized trom dlethyl amine, dichloroethane and lauryl bromide by two steps method based on the alkylation of amine. The chemical structure of the product was confirmed by FT - IR. The surface tension and critical micelle concentration of the Gemini surfactant were determined. The result showed that the Gemini surfactant had high surface activity.
