间接法合成磷酸二乙酯的工艺条件
THE INDIRECT SYNTHESIS OF DIETHYL PHOSPHATE
【摘要】 以磷酸三乙酯 (TEP)为原料间接合成了磷酸二乙酯 ,最佳反应条件为 :TEP/ P2 O5/乙醇 (物质的量比 ) =5∶ 4∶ 8,酯化温度 1 0 0~ 1 1 0℃ ,酯化时间 1 5 h,产物中 w (磷酸二乙酯 )可达 83 .98%
【Abstract】 Diethyl phosphate was synthesized indirectly from triethyl phosphate (TEP) P 2O 5 and ethanol, the optimum conditions were that the molar rato of TEP to P 2O 5 to C 2H 5OH was 5∶4∶8, the reaction lasted for 15 h at 100110 ℃. The content of diethyl phosphate in the product reached 83.87%.
