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 CO 2 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.
