在水溶剂中, 酸性离子液体[bmim][HSO4]可以有效地催化芳香醛与5,5-二甲基-1,3-环己二酮反应3～5 h, 得到产率为76%～86%的芳亚甲基双(3-羟基-5,5-二甲基-2-环己烯-1-酮)类化合物. 该反应产物后处理简单, 催化剂可以回收利用. 催化剂在循环使用五次时对产物的收率影响不大, 是一种环境友好的绿色合成方法.

关键词: 离子液体, 催化活性, 环境友好

Acid ionic liquid [bmim][HSO4] was found to be an effective catalyst for synthesizing aryl-methylene bis(3-hydroxy-5,5-dimethyl-2-cyclohexene-1-ketone) by the reaction of aromatic aldehyde with 5,5-dimethylcyclohexane-1,3-dione in aqueous media. The catalytic reactions were completed during 3～5 h with 76%～86% yields. The catalyst could be recycled and reused five times without noticeable decrease in the catalytic activity. The process is simple and environmentally benign.

Key words: ionic liquid, catalytic activity, environmentally benign
