【Abstract】 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.更多还原
