Abstract

In recent years, CO2 utilisation has been a focus of many chemical industries as an innovative way to reduce the accumulation of anthropogenic CO2. Recent publications show that significant progress has been made in the effective utilisation of CO2 as a value-added products e.g. organic carbonates. Organic carbonates such as propylene carbonate (PC), styrene carbonate (SC) and chloromethyl ethylene carbonate (CMEC) are widely used as polar aprotic solvents, fuel additive and electrolytes for lithium-ion batteries. The development of an efficient and a stable Zr/ZIF-8 catalyst for the synthesis of chloromethyl ethylene carbonate (CMEC) from epichlorohydrin (ECH) and CO2 is a promising greener technology for CO2 utilisation. Incorporating zirconium into ZIF-8 has significantly increased ZIF-8 stability as well as the catalytic performance of Zr/ZIF-8 with the conversion of ECH, selectivity and yield of CMEC being 93%, 91% and 71%, respectively. The catalyst displayed high ECH conversion and high selectivity to CMEC at 80oC. The optimum reaction condition was found at 80oC, 8 bar CO2 pressure and 8 h using fresh 10% (w/w) Zr/ZIF-8 catalyst loading for this reactive system.
