Abstract Dimethyl carbonate (DMC) is a an important green chemical imtermediate anic synthesis. There
are several ways to the synthesis of dimethyl carbonate , in which vapor phase method has many advantages , such as low
erosion , relatively easier separation of products , attainable raw materials etc. This paper reviews the research progress of
the method , including reaction conditions , catalyst preparation , reaction mechanism and ic model. The co product ,
water , in this reaction often causes catalyst deactivation and equipment corrosion. Considering the fact , the coupling of
dimethyl ether (DME) hydrolysis with methanol carbonylation reac
