ABSTRACT:
The present invention relates to a novel catalyst having a stable catalytic activity for catalyzing the reaction of an alcohol with carbon monoxide and oxygen to produce carbonic acid esters (i.e., carbonate), and also the present invention relates to a method of producing carbonic acid esters using this catalyst. The catalyst of the present invention comprises a copper halide and at least one hydroxide compound selected from a group consisting of alkali metal hydroxides and alkali earth metal hydroxides carried on a porous carrier, and also provide a process of regenerating a catalytic activity of the catalyst.
