RECENT DEVELOPMENT OF DIMETHYL CARBONATE SYNTHESIS FROM CARBON DIoXIDE AND METHANOL

Recent progress in the synthesis of dimethyl carbonate(DMC)from carbon dioxide and methanol is reviewed with the focus on the catalysts,including organometallic alkoxides,supported organometallic catalysts,base metal catalysts,metal acetates,oxide catalysts,heteropolyacid catalyst and surface complex photocatalyst.The reaction systems including supercriticat,ion liquid,electro- chemical synthesis,absorbent agent,membrane reactor and microwave technology are also discussed. Synthesis of dimethyl carbonate from carbon dioxide and methanol has the prospect of commercializa- tion.
