文摘A novel tetrabutyl ammonium bromide(TBAB) modified Wacker-type catalyst system supported on various supports has been investigated in the gas-phase oxidative carbonylation of methanol and CO for dimethyl carbonate(DMC) synthesis. It is demonstrated that the SiO 2 supported Wacker-type catalysts have shown the best catalytic performance for DMC synthesis in terms of the activity and selectivity.
