摘要
以三氯化磷、苄醇为原料，以N，N-二甲基苯胺为缚酸剂，石油醚为溶剂，合成了亚磷酸三苄酯。研究了溶剂、反应温度和反应时间对酯产率的影响。结果表明，以60-90℃的石油醚为溶剂，滴加温度5-10℃，反应温度为40-50℃，反应时间为1h，产品收率为80．5％。
Tribenzyl phosphite is synthesized with phosphorus trichloride and benzyl alcohol as starting materials, N, N -dimethyl aniline as acid binding agent and petroleum ether as solvent . The effects of solvent , reaction temperature and time are discussed in details. The results show that, with （60-90℃）petroleum ether as solvent, dropping temperature 5 - 10℃, reaction temperature 40- 50 ℃, reaction time 1 h, the yield of tribenzyl phosphite can be up to 80.5 %.
