摘要： 在K2CO3-Al2O3负载型碱试剂作用下,对苯二酚可发生选择性的单醚化反应。单醚产率高,操作简便。文中讨论了影响单醚产率的各种反应条件和可能的反应机理。

关键词: 对苯二酚, 醚化反应, K2CO3-Al2O3试剂

Abstract: By using Al2O3-supported K2CO3 as a base reagent,the highly selective monoetherification of hydroquinone by alkylating reagents has been carried out in good yield and by simple experimental procedures.A variety of reaction conditions affecting the monoetherification and a probable reaction mechanism were discussed.

Key words: hydroquinone, etherification, K2CO3-Al2O3 reagent
