摘要
对用三氯化磷和醇合成亚磷酸二烷基酯方法进行了改进。讨论了原料配比、反应时间、反应温度、溶剂用量等因素对反应的影响,确定了合成亚磷酸二甲酯和亚磷酸二正丁酯的最佳反应条件,在最佳条件下,二者的产率分别为83.6％和92.7％左右。
The method for synthesizing dialkyl phosphite from phosphorus trichloride was improved. The effects of reactant ratio, reaction time, reaction temperature, and amount of solvent on the reactions were investigated. The optimal reaction conditions were detemined. The yields of dimethyl phosphite and dibutyl phosphite could be up to -83.6% and - 92.7 % respectively.
