摘　　要：以脂肪醇和环氧乙烷为原料,五氧化二磷为酯化剂,三乙醇胺为中和剂,合成了脂肪醇聚氧乙烯醚磷酸酯三乙醇胺盐,对其合成工艺及其复配油剂在腈纶上的应用进行了研究。结果表明,最佳合成工艺条件为:环氧乙烷与脂肪醇的摩尔比为2．0,脂肪醇聚氧乙烯醚与五氧化二磷的摩尔比为3．8,五氧化二磷投料时间1．5 h,酯化温度70℃,酯化反应时间3．0 h,三乙醇胺的加入量是脂肪醇聚氧乙烯醚磷酸酯的0．73-0．76 倍。用酯肪醇聚氧乙烯醚磷酸酯三乙醇胺盐为单体复配的油剂,其在腈纶中的应用情况与进口日本油剂相当。Fatty alcohol polyoxyethylene phosphonate tri-ethanolamine salt was synthesized by using fatty alcohol and ethylene oxide as raw materials, phosphorus pentoxide as an esterification reagent and tri-ethanolamine as a neutralizer. The synthesis process and application of its built finish oil in polyacrylonitrile fiber production were studied. The synthesis process conditions were optimized as followed： mole ratio of ethylene oxide and fatty alcohol 2.0, mole ratio of fatty alcohol polyoxyethylene and phosphorus pentoxide 3.8, phosphorus pentoxide feeding time 1.5 h, esterifieation temperature 70℃ and time 3.0 h, tri-ethanolamine amount 0.73 -0.76 higher times than fatty alcohol polyoxyethylene phosphonate amount. The built finish oil using fatty alcohol polyoxyethylene phosphonate tri-ethanolamine salt as monomer had the performance equal to the imported ones from Japan.
