A process for preparing carbonate esters by the oxidative carbonylation of an alcohol is provided. The process comprises reacting an alcohol with carbon monoxide in the presence of a dihydrocarbyl peroxide the process being characterized by the fact that the carbon monoxide pressure at the reaction temperature is less than 15 bars and by the fact that a catalyst comprising a platinum group metal and a copper compound is employed. The process is useful for preparing dimethyl carbonate from methanol and carbon monoxide.

Preparation of carbonate esters

A process for the production of a dialkyl carbonate, e.g. dimethyl carbonate, or a dialkyl oxalate, e.g. dimethyl oxalate, from butane, oxygen carbon monoxide and an alcohol is provided in a series of integrated process steps. In the case of a dialkyl oxalate, the product can be hydrogenated further to produce an ether of ethylene glycol.

Process for the coproduction of a dialkyl oxalate and tertiary butanol
