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,得到收率约400%的纯氯化二苯基膦
The phenylphosphine chloride was synthesized by one-step method, and the mixture was extracted 20 times with petroleum ether (60-90 ℃) and methylene chloride mixed solvent under atmospheric pressure and vacuum distillation, 142 ° C fraction to give pure chlorinated diphenylphosphine in a yield of about 400%
