Abstract
The catalytic activity of ZIF-8 and amine-functionalized ZIF-8 catalysts in the synthesis of chloropropene carbonate from CO2 and epichlorohydrin is demonstrated. In contrast to hitherto known catalysts, ZIF-8 catalysts displayed high epoxide conversions, and moderate to high selectivities to chloropropene carbonate at reaction temperatures as low as 70°C. No co-catalysts or solvents were required during the reaction. The incorporation of ethylenediamine in ZIF-8 enhanced its catalytic performance due to the higher CO2 adsorption capacity of the aminefunctionalized samples. The ZIF-8 catalysts however, lost their distinctive crystalline structure and superior catalytic performance when attempts were made to recycle them after use.
