叔丁基溴合成方法的改进

An Improved Method of Synthesising Tert-Butyl Bromide

在碱金属溴化物的存在下,氢溴酸的水溶液与叔丁醇反应制取叔丁基溴,产率为70％。反应的残液经蒸馏去水可用于下次合成。如果多次重复利用,氢溴酸的转化率可达90％。

Tert-Butyl bromide has been prepared in 79% yielded by the reaction of the aqueous solution of hydrobromic acid and tert-butyl alcohol in the presence of alkaline metal bromide.Residual solution of the reaction treated with distillation may be used for next synthesis. If residual solution of the reaction is utilized repeatedly, conversation ratio of hydrobromic acid can reach 90%.
