摘要： 以乙二胺、月桂酸、三氯化磷和2-溴乙基磺酸钠等为原料,制备磺酸盐双子表面活性剂乙撑-双(N-乙磺酸-十二酰胺)钠盐,对其中间体合成工艺进行优化,对产物结构进行表征,并对其相关性能如表面活性、起泡性以及乳化性进行测定。结果表明:该表面活性剂的水溶液在24 ℃条件下,其临界胶束浓度(cmc)为0.53 mmol/L,相应表面张力(γcmc)为29.73 mN/m,该表面活性剂的表面活性、起泡性以及乳化性较好。

Abstract: Gemini surfactant bis-(sodium N-ethylene dodecylamide ethyl sulfonate) was prepared with ethylenediamine,lauric acid,phosphorus trichloride and sodium 2-bromo ethyl sulfonate as starting materials.The process conditions for synthesis of the intermediate were optimized and the structure of the final product was characterized.Performance of the final product,such as surface activity,foaming power and emulsifying power were measured.Results showed that aqueous solution of the final product at 24 ℃,the critical micelle concentration (cmc) value is 0.53 mmol/L,γcmc is 29.73 mN/m.It displays good surface activity,foaming power,and emulsifying power.

Key words: Gemini surfactant, bis-(sodium N-ethylene dodecylamide ethyl sulfonate), synthesis, performance
