The process includes the following steps: dissolving bromine in halogenated hydrocarbon, dropping the bromine solution into reactant system comprising pentabromo toluene, halogenated hydrocarbon, free radical initiator and hydrogen peroxide at 50-65 deg.c, and heating to 60-78 deg.c for reflux reaction until the reactant system becomes transparent; filtering the resultant to obtain solid product, washing with carbon tetrachloride and water separately and vacuum drying to obtain pentabromo benzyl bromide.
具体步骤为:将五溴甲苯、卤代烃、自由基引发剂和过氧化氢组成的反应体系加入到三颈瓶中,将0.07~0.1mol的溴溶于50ml卤代烃配成溶液,在50-65℃温度下滴加到反应体系中,滴加时间为50-70分钟,然后升温至60-78℃温度下回流反应,至反应体系逐渐变透明,且不再产生气泡时,将所得产物过滤,得到固体产物,分别用CCl 4 和水洗涤,真空干燥,即得到五溴苄基溴;其中,五溴甲苯与溴的摩尔比为1∶0.7-1∶1.0,溴与过氧化氢的摩尔比为1∶1.0-1∶1.4,自由基引发剂加入量为五溴甲苯重量的1-10%,卤代烃的加入量为反应体系体积的40%-100%,所用溶剂可以直接进行下一批反应,不需要更换溶剂或蒸馏提纯。
