摘要： An alcohol, e.g. methanol, carbon monoxide and oxygen are allowed to react in a gas phase in the presence of a solid catalyst comprising a catalyst component, for instance, containing halogen and copper atoms supported on a solid support. The alcohol and carbon monoxide contents of the reactor feed gas are controlled at 1 to 20 volume % and 70 to 95 volume %, respectively. Because the alcohol and carbon monoxide contents of the feed reactant gas are thus controlled, side reactions are considerably inhibited and the object carbonic diester is produced with high selectivity.

摘要翻译： 酒精，例如 甲醇，一氧化碳和氧气在包含催化剂组分的固体催化剂存在下在气相中反应，例如含有支持在固体载体上的卤素和铜原子。 反应器进料气体的醇和一氧化碳含量分别控制在1至20体积％和70至95体积％。 因为进料反应气体的醇和一氧化碳含量因此受到控制，所以副反应被显着地抑制，并且以高选择性产生目标碳酸二酯。
