摘　　要：描述了一种合成亚磷酸三乙酯的新方法,是由三氯化磷和无水乙醇在氨气存在下发生酯化反应,经碱洗、蒸馏制得亚磷酸三乙酯.收率可达75%.This paper describes a new method for preparing triethyl phosphite. The esterification of phosphorus trichlo-ride with absolute ethanol takes place in the presence of ammonia. The reaction liquid abtained is scoured with alkazid solution,then distillated. and the product is abtained. The product yield is 75%.
