Abstract—The kinetics of the reaction of CO₂ with propylene oxide utilizing a salenCrCl/PPNCl active catalytic system is studied with varying reaction conditions (temperature, pressure, and cocatalyst/catalyst ratio). The reaction proceeds selectively to form cyclic propylene carbonate (PC) at [PPNCl]/[salenCrCl] ratios above two. The value of the effective activation energy of PC formation is found.
