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
