摘　　要：研究了一种新的甲苯上ａ—Ｈ的溴化方法。着重探讨了反应物配比、 反应温度、反应时间及引发条件等对甲苯上ａ—Ｈ溴代反应的影响。实验表明：在 优化的工艺条件下，能获得纯度较高，收率较高的溴化苄。该新方法反应条件温和， 操作简便，溴的利用率高，无腐蚀性气体溴化氢产生。A new method of synthesizing benzyl bromide. has been stadied. Some fac- tors which affect the reaction are also discussed. The results show: in the optimum condition, especially in the condition of oxide agent existing, purer benzyl bromide can be obtained, and the product yield is higher. Furthermore, the new method has the following superiority: mild reaction condition, simple operation, high utilization efficiency of bromine and no poisonous gases emitting.
