    摘要: The present disclosure provides a process for producing dimethyl carbonate with high conversion rate. Alkylene glycol reacts with urea via alcohylysis reaction to produce alkylene carbonate and ammonia. The alkylene carbonate produced reacts with methanol via transesterification reaction to produce dimethyl carbonate. Before the dimethyl carbonate is separated from the mixture, the nitrogen-containing impurities are substantially removed. Unreacted feedstock and catalysts are recycled in the process.

    摘要: A catalyst which can catalyze ring-addition reaction of CO2 and an alkylene oxide at 0˜180° C. under 0.1˜8.0 MPa to produce a corresponding cyclic carbonate, and the preparation thereof. The catalyst is a conjugated microporous macromolecule polymer complexed with cobalt, chromium, zinc, copper or aluminium, and by using the macromolecule catalyst complexed with different metals to catalyze the reaction of CO2 and alkylene oxide at normal temperature and normal pressure, a yield of the corresponding cyclic carbonate of 35%-90% can be obtained. The catalyst is easy to recover and the re-use of the catalyst has no influence on the yield; additionally, the yield can reach over 90% by controlling the reaction conditions.
