process for preparing cyclic carbonate using hyper crosslinked polymers and hyper crosslinked polymers for selective formation of cyclic carbonates

摘要

The present invention uses a crosslinked biphenyl polymer as a catalyst, and uses a epoxide compound of various structures and carbon dioxide as a raw material to selectively produce cyclic carbonates at a high yield with a high conversion rate compared to conventional catalysts, and a supercrosslinked bi It relates to a phenyl polymer.
