The synthesis of cyclic carbonate from CO 2 and alkylene oxide is one of the best
environment-friendly technologies for converting CO 2 to valuable chemicals. In this study, a
[ZnX 2 Cl 2] 2− immobilized ion exchange resin (ZnX 2/IER) was synthesized using four
kinds of zinc precursors, ZnX 2 (X= Cl, Br, OAc, and NO 3) and a chloride-anion exchange
resin (IER). The synthesized ZnX 2/IER was then used for the cycloaddition reaction of CO 2
and propylene oxide (PO) to synthesize propylene carbonate (PC). Among the synthesized …
