对溴苯甲醚合成条件的改进

Improvement on Preparation of p Bromophenylmethylether

探讨反应条件、试剂用量以及改进的两条合成路线对合成对溴苯甲醚产率的影响。经改进的合成方法反应条件从 140℃～ 15 0℃降至 70℃～ 80℃ ,操作简便 ,产率从 6 0 %提高到 82 %～ 87.4%。

The effects of the reaction temperatures, the quantities of the reagents and two methods of synthesizing p bromoanisole on the reaction yields were discussed. Compared with the methods of the literatures reported, both of the improved methods are better than those to the experiment conditions and the reaction yields.The reaction temperature declined to 70℃ to 80℃ from 140℃ to 150℃.The reaction yields increased to 82% to 87 4% from 60%.
