二元醇与三氯氧磷的酯化反应研究

Study on Esterification Reaction of Diols and Three Phosphorus Oxychloride

双子表面活性剂有非常低的CMC值和很高的界面活性。在生物医药与生物分离、纺织和皮革助剂以及农用化学品和化妆品等领域有良好的应用前景。文章以乙二醇和三氯氧磷为原料,经过酯化反应合成阴离子双子表面活性剂中间体——乙二基二氯磷酯。通过单因素实验法考察了反应时间,反应温度及催化剂对反应产率的影响,确定了实验合成的最佳条件。

Gemini surface active agent has very low CMC values and high interfacial activity. In the field of bio medicine and biological separation, textile and leather auxiliaries and agricultural chemicals and cosmetics have good application prospects. In the paper, the first step reaction of anionic gemini surfactant intermediates with ethylene glycol and three chloride as raw materials, the first step reaction of anionic gemini surfactant intermediates was synthesized by two two P Reaction time were investigated by single factor test, effects of reaction temperature and catalyst on the reaction yield, to determine the experiments the optimum conditions for synthesis.
