ABSTRACT:
Process for the preparation of dimethylcarbonate which consists in feeding oxygen and a mixture of methanol and carbon monoxide to the reactor, with a molar ratio methanol/carbon monoxide of between 1 and 2, this mixture coming directly from the non catalytic direct oxidation of methane with oxygen characterized in that the above molar ratio between methanol and carbon monoxide, with fixed temperature and pressure values, is obtained by maintaining the ratio between methane and oxygen between 1 and 100, by injections of fresh oxygen into a tubular reactor, during the above oxidation reaction.
