Abstract: PROBLEM TO BE SOLVED: To produce the subject compound in high yield without consuming great energy and without deteriorating the activity of a catalyst by reacting dimethyl ether with carbon monoxide and oxygen in the presence of a copper compound and a platinum group compound. SOLUTION: A catalyst composed of a copper compound (e.g. anhydrous cupric chloride) and a platinum group compound (e.g. palladium chloride) and dimethyl ether are charged into a magnetic stirring type autoclave and the interior of the autoclave is sufficiently replaced with carbon monoxide, which it then pressurized at normal temperature to 30 kg/cm<2> . Oxygen is further added thereto and pressure is increased to 45 kg/cm<2> to hermetically seal the autoclave. The temperature is then increased while stirring the 5 hr. The autoclave is directly cooled with water and the gas is decompressed to take out the resultant reactional product. Thereby, the objective dimethyl carbonate is obtained in high yield without deteriorating the activity of the catalyst.
