【Abstract】 According to the main problem of current domestic synthesis of o-chlorobenzyl chloride, study was made to increase the reaction conversion to 60% by using new catalyst CHJ-3; compare with general catalyst, the reaction time has saved a half, and the reaction conversion increased 50%. Therefore, the production cost was reduced.. The results indica- ted that the improvement is of remarkable economic and social benefits with prospects of being applied extensively.更多还原
