【摘要】 利用酒石酸与月桂酰氯反应合成一种新型双子表面活性剂双月桂酰酒石酸酯,探讨了物料配比、反应时间等因素对产品收率的影响,结果表明合成反应的最佳条件为n(月桂酰氯):n(酒石酸)为2．2:1,反应时间为3．0h,产品收率可达86％．产品具有良好的表面活性,与月桂酸钠相比具有更低的临界胶束浓度．更多还原

【Abstract】 The new gemini surfactant, di-lauroyl tartaric acid ester, was synthesized from tartaric acid and lauroyl chloride. The effect of ration of raw materials, reaction time on the yield of product was investigated. The optimum synthetic conditions were as follows: the mole ratio of tartaric acid and lauroyl chloride 2.2 : 1, reaction time 3.0h, and the highest yield of product was around 86%. The product has good surface activity and lower critical micelle concentration (CMC) compared with sodium lauric acid.更多还原
