For the first time the reaction of catalytic oxidative coupling of dimethyl ether (DME) in supercritical conditions is investigated. Oxidation of dimethyl ether by molecular oxygen in the presence of a СаO—SnO2 catalyst was carried out in the medium of excess reactant (DME) and in its mixtures with carbon dioxide in supercritical (SC) conditions (100 atm, 250—300 °C). At 255 °C a maximum conversion of DME (approaching 40 % at monoglim: diglim ratio about 2:1) is reached at 20-fold (by volume) dilution of DME with SC-CO2.
