摘　　要：以苯和三氯化磷为原料,在气相色谱监控下,以[bpc]Br-xAlCl3离子液体作为催化剂催化合成苯基二氯化膦(DCPP),讨论反应时间、催化剂用量、催化剂的重复使用性等因素对DCPP产率的影响.研究表明,使用气相色谱对实验进行监控有效地缩短了实验周期、提高了工作效率,使用[bpc]Br-xAlCl3离子液体催化合成DCPP时具有催化剂用量少、催化效率高、催化剂具有一定的重复使用性、产品可直接分离、环境污染小等特点.The Friedel-Crafts reaction of PC13 and benzene in [bpc]Br-xAlCl3 ionic liquids was investigated for green synthesis of dichlorophenylphosphine（DCPP）with real time monitoring of gas chromatography（GC）. Reaction time,the efficiency of catalyst,performance for repeated use of ILs were studied. It was found that the experimental cycle was shorten by using GC, [bpc]Br-xAlCl3 was a high efficiency of catalyst and has good performance for repeated use ,DCPP could be seperated easily and has little environmental pollution.
