Process for producing carbonic acid ester |
| abstract |
Disclosed herein is a process for producing a carbonic acid ester by reacting alcohol, carbon monoxide, and oxygen with one another in the presence of a copper compound alone or together with a platinum metal compound and a reaction accelerator, characterized in that (I) the reaction is carried out in a nitrile compound or amide compound as a solvent, (II) the reaction is carried out in the presence of a reaction accelerator which consists of a quaternary phosphonium halide and a quaternary phosphonium weak acid salt or quaternary phosphonium alkoxide, and/or (III) the reaction is carried out in the presence of a quinoid compound or a compound that changes into a quinoid compound under the reaction condition. |
