中文摘要：以苯和三光气为主要原料,经Friedel-Crafts酰化、还原和氯化三步反应得到二苯氯甲烷。该工艺使用"绿色试剂"三光气作为酰化和氯化试剂,反应条件温和,操作方便,副产物少,后处理简单,环境污染小,三步总收率达到45.3%。

外文摘要：Diphenylchloromethane had been synthesized from benzene and triphosgene as the main raw materials after the three steps of Friedel-Crafts acylation, reduction and chlorination. Triphosgene, as a ＂green reagent＂, had been used as the acylating and chlorinating agent in the thecnics, which made this method milder reaction conditions, fewer byproduts, convenient operation and environmently benign. The overall yield of the three-step was 45.3 %.
