氯化二苯基膦制备方法的改进

Improved preparation of chlorodiphenylphosphine

采用一步法合成氯化苯基膦,用二氧六环破坏配合物,石油醚(60～90℃)和二氯甲烷混合溶剂提取20次,常压、减压蒸馏,在04kPa下收集140～142℃馏分。

The synthesis of chlorophenylphosphine in one step procedure is reported.The complex was destroyed by using of dioxane,then extract the mixture with the solvent of petroleum ether(60～90℃) and methylene dichloride for 20 times.The solvent were removed and the residue was distilled under reduce pressure(140～142℃,0 4 kPa)to give pure chlorodipenylphosphine which yield was 40%.
