英文摘要: A series of hydroxyl-functionalized ionic liquids such as dialkyl (or alkyl) di-(tri-) hydroxyethyl ammonium hydroxide, tetrahydroxyethyl ammonium hydroxide and alkylhydroxyethyl or dihydroxyethyl immidazolium hydroxide were synthesized and characterized by FT-IR and 1H NMR. These ionic liquids containing hydroxyls were used as catalysts for direct synthesis of dimethyl carbonate (DMC) from methanol and carbon dioxide. The results showed that benzylmethyldihydroxyethyl ammonium hydroxide (BzMDH) is an effect catalyst with raised catalytic activity and high selectivity to DMC. The effect of hydroxyl groups on the activation of methanol and CO2 were explored. Furthermore, the reaction mechanism of this synthetic reaction was discussed. © 2015 Elsevier Ltd.
