摘要: A process for producing an oxalate diester is provided. The oxalate diester is produced by reacting an aliphatic alcohol, carbon monoxide and molecular oxygen at an elevated temperature and under pressure in the presence of a catalyst comprising (1) metallic palladium or a palladium compound, (2) a heteropoly-acid and (3) at least one nitrogen compound selected from the group consisting of nitric acid, nitrogen oxides and esters of nitrous acid.
