Dimethyl carbonate synthesis by oxidative carbonylation on activated carbon supported CuCl_2 catalysts:catalytic properties and structural change

摘要

Catalytic properties of CuCl_2 catalysts supported on activated carbon in the synthesis of dimethyl carbonate by oxidative carbonylation of methanol were investigated. Structural changes during the reaction were studied. It was suggested that dimethyl carbonate formation rate is strongly realted to Cl/Cu ratio and CO formation rate is higher on the catalyst with Cu oxychloride than on that with Cu-Cl-OH.
