Hydroxy-containing ionic liquids such as triethyl(3-hydroxypropyl)ammonium, 1-(3-hydroxypropyl)-3-methylimidazolium, 3-(2-hydroxyethyl)-1-methylimidazolium, and 1-(3-hydroxypropyl)pyridinium chlorides were used as catalysts for the addition of carbon dioxide to epoxides, which gives cyclic carbonates. The effect of CO2 pressure and reaction temperature on the conversion of epoxides, as well as a promoting effect of inorganic substrates were studied.
含羟基的离子液体,如三乙基(3-羟基丙基)铵盐、1-(3-羟基丙基)-3-甲基咪唑盐、3-(2-羟基乙基)-1-甲基咪唑盐和1-(3-羟基丙基)吡啶铵氯化物,被用作催化剂,促进二氧化碳与环氧化合物的加成反应,从而生成环状碳酸酯。研究了二氧化碳压力和反应温度对环氧化合物转化率的影响,以及无机底物的促进作用。
