METHOD FOR PRODUCING CYCLIC CARBONATES

摘要

Linear or cyclic carbonates as potential monomers for isocyanate-free polyurethanes and polycarbonates were prepared from polyols and dialkyl carbonates or diphenyl carbonates. This invention was developed to produce linear or cyclic carbonates with or without using catalysts. Polyol compounds were reacted with carbonates such as dimethyl carbonate and diethyl carbonate to produce the corresponding linear and/or cyclic carbonate.
