摘要 对以邻硝基甲苯为原料,NaBrO3/NaHSO3为溴化剂,偶氮双异丁腈(AIBN)为引发剂,制备邻硝基苄基溴的工艺路线进行了研究,在优惠的工艺条件下n(邻硝基甲苯)∶n(溴酸钠)∶n(亚硫酸氢钠)=1∶4∶4,反应温度70℃,时间2h,反应收率≥73%。该工艺具有生产成本低、操作简便和易于工业化生产等特点。 A new method of preparation o-nitrobenzyl bromide using o-nitrotoluene as raw material, NaBrO3/NaHSO3 as bromination agent and AIBN as initiator was developed, under the optimum conditions n (o-nitrotoluene) :n (sodiumbromate) :n (sodiumbisulfite)=1:4:4, reaction terperature 70 ℃, reaction time 2 h, the yield is up to 73%. This process is easy to scale up with lower material cost, simple and convenient operation.
