利用未液化处理的工业氯气制备三氯甲苯的工艺条件初步研究

Preliminary study on the process conditions of the preparation of the trichlorotoluene by the unliquefied industrial chlorine

在自然光照条件下,用三乙醇胺作副反应抑制剂、过氧化苯甲酰作催化剂,利用未液化处理的工业氯气和甲苯制备三氯甲苯,通入氯气反应,三氯甲苯最高收率达到95.85%。

Under natural light conditions,trichlorotoluene was prepared by using triethanolamine as the by-product inhibitor and benzoyl peroxide as the catalyst,using unliquidated industrial chlorine and toluene.The highest yield of trichlorotoluene was 95.85%.
