摘　　要：将氯化亚铜负载在纳米炭上作为催化剂，二乙胺为助催化剂，苯乙烯和四氯化碳发生加成反应生成1，3，3，3-四氯丙烯苯中间体，其收率为96．0％。此负载型催化剂具有催化活性高，稳定性好，易分离等优点。中间体于酸性体系中在115～125℃下水解12h，结晶过滤得到产物肉桂酸。The intermediate 1,3,3,3 -tetrachloropropyl benzene was synthesized from styrene and carbon tetrachloride with the cuprous chloride loaded on nano-carbon as catalyst and diethylamine as cocatalyst. The yield was 96.0%. The supported catalyst has the qualities of high catalytic activity, good stability, can be separated easily etc. In the acidic system with the temperature of 115-125 ℃, the intermediate hydrolyzed in to cirmamic acid within 12 h.
