Direct synthesis of dimethyl carbonate offers prospects for a “green chemistry” replacement to eliminate use of phosgene for polymer
production and other processes. The carbonylation of methanol to produce dimethyl carbonate over Cu+X and Cu+ZSM-5 zeolites prepared
by solid-state ion exchange has been investigated, focusing on the interaction of carbon monoxide with the Cu+ zeolites. The methanol
carbonylation mechanism reported previously has been extended to account for carbon monoxide adsorption at high pressure. The comparison
of the results obtained from Cu+X and Cu+ZSM-5 show that strong CO adsorption on the catalyst is not related to increased rate of dimethyl
carbonate production. The rate limiting step for DMC production is best described as the Eley-Rideal reaction of gas-phase CO with surface
