Continuous-flow synthesis demonstrates high yields of cyclic carbonate in various epoxide substrates, suggesting its potential in the chemical industry.
Supercritical carbon dioxide (scCO 2 ) is well‐known for its low viscosity and high diffusivity, which are widely utilized in CO 2 transportation and storage processes within the carbon capture, utilization, and storage (CCUS) strategy. Additionally, its strong solvation capacity, environmental benignity, and facile separation make it an attractive solvent for organic synthesis. In this study, we successfully apply scCO 2 in CO 2 cycloaddition with epoxides for continuous cyclic carbonate synthesis using our developed imidazolium‐based polymer‐supported ionic liquid (Im‐PSIL) catalysts. The application of this scCO 2 ‐assisted catalytic system to five different epoxide substrates, including essential industrial chemicals such as epichlorohydrin and glycidol, delivered moderate to excellent yields, highlighting its high value for the chemical industry.
