The reaction of cyclohexene oxide with CO2 to synthesize cyclohexene carbonate

catalyzed by a complex catalyst

under 1.4—2.6 MPa of pressure

at 130—170℃ of temperature was studied experimentally.After eliminating the influence of external diffusion

the rate constants of positive and reverse reactions were estimated by fitting the experimental data to a macro-kinetics model.The results indicated that the reaction was an exothermal reaction.The reaction heat was -42.11 kJ8226;mol-1.The activation energy was 27.51 kJ8226;mol-1 for the positive reaction

and 69.66 kJ8226;mol-1 for the reverse reaction.
