Abstract:Bicyclohexane-4, 4'-dione mono-ethyleneketal, a key thin film transistor (TFT) liquid crystal intermediate, was synthesized with BMImH_2PO_4 as a solvent and catalyst. The results show that the reaction of bicyclohexane-4,4'-dione and glycol in BMImH_2PO_4 proceeds smoothly at 130℃ for 1 h to afford bicyclohexane-4,4'-dione mono-ethyleneketal with the yield of 68.7% and selectivity of 83.4%. The ionic liquid method is with the advantages of high yield and selectivity, ease of product separation, environmental benign and recycle of ionic liquid, and is significant for its promising industrial application.
Keywords:ionic liquid  bicyclohexane-4,4'-dione mono-ethyleneketal  synthesis
