摘　　要：在Ｋ＿２ＣＯ＿３－Ａｌ＿２Ｏ＿３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．By using Al2O3-supported K2CO3 as a base reagent,the highly selective mo-noetherification of hydroquinone by alkylating reagents has been carried out in good yield andby simple experimental procedures.A variety of reaction conditions affecting the monoethe-rification and a probable reaction mechanism were discussed.

关 键 词：对苯二酚 碳酸钾碱试剂 醚化反应
