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1倍,反应转化率提高50%,从而有效地降低生产成本,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 existing problem of o-chlorobenzyl chloride production process at home, application of new XJ-2 catalyst and the innovation of catalytic and chlorination process, the conversion of tolylchloride was 60% in chlorination reaction. The reaction was one times shorter than the traditional catalyst, and the reaction conversion ratio increased 50%. The cost was reduced effectively. The economic profits and social benefit was obvious with the prospects of being applied extensively.
