摘　　要：研究了在惰性非极性溶剂和部分惰性极性溶剂中 ,以苯酚为原料进行直接溴化反应的溶剂效应、温度效应、浓度效应及催化剂的选择效应。得到了直接一元溴化反应的适用溶剂有惰性非极性溶剂及部分惰性极性溶剂。The effects of different solvents, temperatures, concentrations and catalysts on the ratio of p-bromophenol,o-bromophenol and 2,4-dibromophenol in the direct bromination of phenol.The results showed that both some inert non-polar solvents and some inert polar ones were suitable as solvents for direct mono-bromination of phenol.A simple, economical and safe method to prepare the desired products was obtained.
