摘　　要：以月桂醇和磷酸为原料,采用固体超强酸催化制备烷基磷酸酯。探讨了催化剂用量、原料配比、反应时间和温度等因素对产品收率的影响。结果表明,最佳反应条件为:n(醇)∶n(酸)=2∶1,反应时间4 h,反应温度120℃,以甲苯共沸带水,催化剂用量为总物料质量的0.4%。A alkyl phosphatic ester was synthesized from lauryl alcohol and phosphoric acid in the presence of solid superacid. The factors influencing the synthsis were discussed and the best conditions were found out. The optimum conditions were： molar ratio of lauryl alcohol to phosphoric acid was 2 ： 1, the quantity of catalyst was equal to 0.4 % feed stock ,the reaction time was 4 h, and the reaction temperature was 120 ℃.
