Abstract:

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 kJ•mol^-1.The activation energy was 27.51 kJ•mol^-1 for the positive reaction, and 69.66 kJ•mol^-1 for the reverse reaction.
