Synthesis of Cyclic Carbonate from CO<sub>2</sub> and Epoxide Catalyzed by Phosphonium Halides ILZinc Halide

Abstract An efficient Lewis acid/base catalyst composed of zinc chloride and trihexyl(tetradecyl)phosphonium bromide ionic liquid was developed and showed surprisingly high activities for the coupling reaction of CO₂and epoxides.The effects of reaction temperature，CO₂ pressure，time and various compositions of the catalyst have been investigated systematically.A high PC yield（95%）could be reached at 100 ℃ with a low CO₂pressure(2 MPa)for 15 min in the presence of [(C₆H₁₃)3P(C₁₄H₂₉)]Br/ZnCl₂ (molar ratio is 2∶1).The catalyst was also applicable to the coupling reaction of CO₂ and other epoxides.At the end，a possible reaction mechanism of the catalyst was proposed.
