Two methods of producing high purity dimethyl carbonate through the reaction of carbon dioxide and methanol are provided. In the ammonia-based method ammonia and carbon dioxide react to produce urea. The urea is mixed with methanol for further reaction to produce dimethyl carbonate. Ammonia released in the process is recycled as a reactant to produce more urea. In the ethylene-oxide process carbon dioxide reacts with ethylene oxide to produce ethylene carbonate. It is then reacted with methanol to produce dimethyl carbonate with ethylene glycol as byproduct. An integrated reactive distillation process using side reactors is used for facilitating catalytic reaction in these two methods for producing high purity dimethyl carbonate. The process is further enhanced by enclosing multiple side reactors into a pressure vessel and incorporating thermal heat pump for recovery and reuse of latent heat within the process.
