-
摘要: 以三氯化磷为催化剂,针对氟甲苯在不同的温度及光照条件下进行侧链氯化取代反应。其连串反应产物分布规律在一定的氯化深度范围内符合一级反应动力学。反应产物组成分布受到光照及温度的影响,α,α-二氯-对氟甲苯的收第在68%~75%。Abstract: For the side chain chlorination of p fluorotoluene under the catalysis of PCl 3, the products distribution of the consecutive reaction within the given limit of chlorination level is in agreement with that predicted the first order reaction kinetics and depends on the light source and temperature. The experimental results show, the yield of p fluorobenzalchloride being 68%~75%.
