摘　　要：针对目前国内邻氯氯苄生产工艺存在的主要问题,通过选用新型催化剂XJ-2,改进催化氯化工艺,使氯化反应邻氯甲苯转化率达到60%。与传统催化剂相比较,氯化反应时间缩短一倍,反应转化率提高50%,从而有效地降低了生产成本,经济效益和社会效益显著,具有很好的推广应用价值。According to the main problem of current domestic synthesis of o-chlorobenzyl chloride, effective improvement has been studied to increase the reaction conversion to 60% by using new catalyst XJ-2;compare with general catalyst, the reaction time has saved a half, and the reac- tion conversion increased 50%. Therefore, the production cost was reduced.. The results indicated that the improvement is of remarkable economic and social benefits with prospects of being applied extensively.
