摘　　要：以脂肪醇聚氧乙烯聚氧丙烯醚为原料,研究了反应温度、反应时间、物料配比对羧甲基化反应的影响,通过一系列实验确定了合成最低界面张力体系的最佳实验条件,并对最佳合成条件下的脂肪醇聚氧乙烯聚氧丙烯醚羧酸盐的性质进行了探讨,脂肪醇聚氧乙烯聚氧丙烯醚羧甲基化后其界面张力得到改善。Polyoxyethylene polyoxypropylene ether carboxylate of fatty alcohol is prepared with polyoxyethylene polyoxypropylene fatty alcohol as raw material by the method of carboxy methylation.Through the studies on the effect of reaction temperature,reaction time and the ratio of reactants in a series experiments,the optimum reaction conditions are obtained. In addition,the interfacial tension performance of the polyoxyethylene polyoxypropylene ether carboxylate of fatty alcohol in the optimum reaction conditions is determined.The interfacial tension is improved.
