CO direct esterification to Diemethyl oxalate and dimethyl carbonate: the key functional motifs for catalytic selectivity
Zhi-Qiao Wang,ab Jing Sun,ab Zhong-Ning Xu *ab and Guo-Cong Guo *ab
, Nanoscale, Issue 39, 2020
The direct esterification of CO involves processes using CO as the starting material and ester chemicals as products. Dimethyl oxalate (DMO) and dimethyl carbonate (DMC) are two different products of the direct CO esterification reaction. However, the effective control of the reaction pathway and direct synthesis of DMO and DMC are challenging.

What should people do with the huge amount of CO2 captured? CO2 to CO is a promising way for using carbon resources because CO is one component of syngas for the production of many important synthesis intermediates such as dimethyl oxalate (DMO). Hydrogenation of DMO provides an economical and eco-friendly approach for the synthesis of methyl glycolate, ethylene glycol (EG), and ethanol, which is often determined by the reaction conditions and catalysts with different active sites.
