摘　　要：采用直接酯化法由月桂醇和三氯化磷来制备亚磷酸三月桂醇酯(TLP)。通过对比实验确定了以吡啶为缚酸剂、苯为溶剂。用正交试验法确定了适宜的合成条件为:反应温度60℃,溶剂用量70 g,滴加时间控制在90 m in,反应时间为90 m in,三氯化磷0.05 mol,月桂醇和三氯化磷的摩尔比为3.1∶1,合成产率可以达到96.2%。Trilauryl phosphite ester was synthesized via the direct esterification reaction of lauryl alcohol and PCl3. When pyridine and benzene were used as the binding reagent of HCl and the solvent, respectively, from the orthogonal experiments, the suitable synthetic conditions were determined as follows：the reaction temperature was 60℃, the solvent quantity was 70 g, the dropwise time was 90 min, reaction time was 1.5 h, and the molar ratio of lauryl alcohol to PCl 3. 1： 1. Under the above conditions, the yield was 95.9%. The quality of the product is as good as one of the overseas.
