Influence of reaction parameters on the cycloaddition reaction of CO2 with propylene oxide. The yield remarkably increased from 58 to 97% when the CO2 pressure was increased from 0.6 to 1.0 MPa and after that the yield maintained constant. The catalytic reaction finished in 4 h, whereas longer reaction time caused a slightly decrease of yield. This is maybe due to the side reactions like polymerization of PC. The optimal reaction temperature was 120 °C
