英文摘要：

The coupling reaction ofpropylene and CO2 to form propylene carbonate （PC） was promoted by an ionic liquid （IL） covalently bound to polyethylene glycol （PEG）. The supported ionic liquid, which has both acidic and basic components, proved to be an active catalyst for PC synthesis under mild conditions. The effects of different cations and anions, reaction temperature, CO2 pressure, and reaction time were investigated. It was demonstrated that the acid group in the catalyst plays an important role in the reaction. With this system, a high PC yield （95%） was achieved under mild conditions （3.0 MPa, 120℃ and 4 h） without a co-solvent. In addition, the catalyst was readily recovered and reused. Based on the experimental results, a plausible mechanism for the catalyst was proposed.
