摘要： A method for co-production of high purity dimethyl carbonate and mono-ethylene glycol by applying a reactor, such as a membrane reactor and/or an adsorbent-catalytic reactor by capturing and reacting carbon dioxide with methanol and ethylene oxide. Carbon dioxide may be recovered from primary sources (utilities and industrial processes) by a membrane or solid adsorbent, and subsequently converted to an intermediate hydroxy-ethyl-methyl carbonate by reacting with ethylene oxide and methanol. For high-purity carbon dioxide (obtained by carbon capture technologies or from an ethanol fermentation process), the membrane reactor is replaced with a catalytic reactor for direct conversion of carbon dioxide to hydroxy-ethyl-methyl carbonate by reacting with ethylene oxide and methanol. The hydro-ethyl-methyl carbonate is further reacted with methanol for conversion to dimethyl carbonate. A combination of heterogeneous and homogeneous catalysts is implemented for an effective conversion of carbon dioxide. An integrated reactive distillation process using side reactors is used for facilitating catalytic reaction for production of high purity dimethyl carbonate.

摘要： Diaryl and substituted diaryl carbonates are formed by a series of steps, the first step involving the production of a dialkyl carbonate from an alkanol, carbon monoxide and oxygen; and the second step involving the reaction of the dialkyl carbonate with a phenyl ester or substituted phenyl ester in the presence of a dialkyl tin compound to produce a mixture of diaryl carbonate, alkyl aryl carbonate, and an alkyl ester. The alkyl ester can be heated to reform the alkanol and form ketene; in turn the ketene can be reacted with the phenol or substituted phenol to form the phenyl ester or substituted phenyl ester used in the second step above.
