摘　　要：以长链烷基叔胺、氯乙醇、环氧氯丙烷、PEG200和五氧化二磷为原料,合成了聚醚基磷酸酯盐两性表面活性剂。确定最佳的合成工艺条件为:烷基醇与P_2O_5的物质的量之比为2.5:1,酯化温度80℃,酯化时间6 h,加水量2%,水解温度75℃,得到的产物单酯含量均大于73%。合成的聚醚磷酸酯盐具有良好的抗静电性和较好的乳化性。Alkyl tertiary amine, chlorohydrin, epichlorohydrin, PEG200 and phosphorus pen-toxide are taken as raw materials to synthesis a novel polyether amphoteric surfactants of alkyl phosphate. The opti- mum process condition is： molar ratio of alkyl alcohol to P2O5 is 2.5 ： 1, esterificating at 80℃ for 6 h, addition of 2% water, hydrolysis temperature of 75℃. The monoester content of product is higher than 73%. The synthetic polyether phosphate salt has good antistatic and emulsification properties.
