A Novel Route for Carbon Dioxide Cycloaddition to Propylene Carbonate

A combination of KI supported catalysts on different supports with a novel continual structural reactor for the production of propylene carbonate from CO2 cycloaddition was investigated in this paper. With neither solvents nor promoters in this synthesis, both propylene oxide conversion and propylene carbonate selectivity were nearly 100% at moderate conditions over the supported catalysts. In the structural reactor, the lifetime of the catalysts can be highly improved with a much higher yield of propylene carbonate, compared to that obtained from the conventional reactor.
