Catalytic oxidative coupling of dimethyl ether (DME) is studied for the first time under supercritical conditions. The oxidation of DME with molecular oxygen of air in the presence of the CaO-SnO2 catalyst is carried out in a substrate (DME) medium and in its mixtures with CO2 under the supercritical conditions (100 atm, 250–300°C). At 255°C, the maximum conversion of DME (≈40% at the ratio of the yields of monoglim and diglim about 2: 1) is achieved at a 20-fold (by volume) dilution of DME with supercritical CO2.
