【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CHJ-3,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。更多还原

【Abstract】 According to the main problem of current synthesis of o-chlorobenzyl chloride in our country,effective improvement was studied to increase the reaction conversion to 60% by use of a new catalyst CHJ-3.The new catalyst would shorten a half of the reaction time and increased the reaction conversion 50% compared with general catalyst,and reduced the production cost.The results indicated that the improvement had an obvious economic and social benefits,and was worthy of extensions and applications更多还原
