ABSTRACT:
The destructive oxidation of oxalic acid is catalyzed by a vanadium compound in liquid phase oxidation. The oxalic acid is contacted with oxygen in the presence of a vanadium compound in aqueous solution and the oxidation proceeds selectively without any appreciable oxidation of other components of the reaction medium such as acetaldehyde and ethylene. The oxidation is performed at temperatures between 30.degree. and 300.degree.C. and atmospheric or superatmospheric pressure.
