PROBLEM TO BE SOLVED: To provide a gas-phase method, for producing a dialkyl carbonate by decarbonylating a dialkyl oxalate, which allows high-yield and highly selective production of a dialkyl carbonate, and easy separation/recovery of products and a catalyst. SOLUTION: This method comprises the steps of (1) catalytically reacting carbon monoxide with alkyl nitrite to form dialkyl oxalate and nitrogen monoxide, and (2) decarbonylating the obtained dialkyl oxalate into a dialkyl carbonate and carbon monoxide. |
