摘 要:文章以甲苯为原料,经溴化反应首先得到中间体五溴甲苯,然后进一步溴化得到阻燃剂五溴苄基溴。中间体的溴化采用紫外光照射和添加热引发剂偶氮二异丁腈(AIBN)的方法,反应速度快、转化率高。用红外和核磁图谱对两种化合物进行了表征。In the present work, flame retardant pentabromobenzyl bromide was synthesized in two steps. Raw material toluene was firstly brominated to prepare pentabromotoluene, which was then further treated with UV light and thermal initiator 2,2'- azo -bis -isobutyronitrile (AIBN) to obtain the target product. The FT - IR and HNMR spectra of the intermediate and final product were recorded. Meanwhile, the result showed that the method is of high reaction speed and convertion rate.
