摘要
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3~5h,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.
Acid ionic liquid bmimHSO4 was found to be an effective catalyst for synthesizing arylmethylene bis(3-hydroxy-5,5-dimethyl-2-cyclohexene-1-ketone) by the reaction of aromatic aldehyde and 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.
