| titleOfInvention | Process for continuously producing dimethyl carbonate |
| abstract | A process for producing dimethyl carbonate is carried out by a first step of catalytically reacting carbon monoxide with methyl nitrite to produce dimethyl carbonate; a second step of absorbing dimethyl carbonate contained in a gas fraction withdrawn from the first step by dimethyl oxalate; a third step of regenerating methyl nitrite by contacting nitrogen monoxide contained in a gas fraction withdrawn from the second step with a molecular oxygen-containing gas and methyl alcohol; a fourth step of collecting dimethyl carbonate by distilling a liquid fraction withdrawn from the second step; and a fifth step of recovering methyl nitrite from a purge gas consisting of a portion of a regenerated gas fraction withdrawn from the third step by absorbing methyl nitrite in the purge gas by methyl alcohol to provide a methyl nitrite-containing liquid fraction and a nitrogen monoxide-containing gas fraction and bringing the gas fraction into contact with a molecular oxygen and methyl alcohol, to convert nitrogen monoxide in the gas fraction to methyl nitrite and to absorb this methyl nitrite by methyl alcohol, whereby methyl nitrite and nitrogen monoxide in the purge gas is recovered and reused with a high efficiency at a high level of safety. |
