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。

Results: Restaging showed 14 cases with stage ⅢA disease, 11 with stage ⅢC, 1 with stage IVA and 3 with stage IVB. The overall 5-year survival for all patients was 48.3%, and for stage Ⅲ patients was 52%. There were four patients with stage IV disease, three of them died during the follow-up. In addition, the overall 5- year survival rate was statistically higher in grade 1 and 2 than in grade 3 in superficial myometrial invasion and in the radiation group.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
