摘要
芳烃化合物芳环氯化选择性无论在经济上 ,还是在环境保护上都具有重要意义。本文综述了芳烃化合物包括甲苯、邻二甲苯、卤代苯、氯苄等选择性氯化研究进展 ,介绍了两类主要的催化体系 ,即路易斯酸和含硫助催化剂组成的催化体系及沸石催化体系。指出以沸石分子筛为催化剂进行芳烃化合物芳环选择性氯化是今后研究方向。
Selectivity is an important consideration in the chlorination of aromatic compounds both in ecnomics and in environmental friendliness Advance in selective nuclear chlorination of aromatic compounds including toluene,o-xylene,halobenzene,chlorobenzy1 chloride,is presented in this paper The catalyst systems consist of Lewis acid and orgnic sulfur co-catalyst and zeolites catalyst system are introduced,especially K-L zeolite catalyst system It is pointed out that selective chlorination catalyzed by zeolites is the main development trend
