This method initially used palladium and copper salts as catalysts, and carried out a liquid-phase coupling reaction of carbon monoxide, oxygen, alcohol, and dilute nitric acid at 8–11 MPa and 90–100 °C. The reaction first produces oxalate ester, which is then hydrolyzed under heating conditions to form oxalic acid and the corresponding alcohol.
This method has a single catalyst system, high activity, good selectivity, easy recovery, high product purity, and low production pollution. However, it has high requirements for carbon monoxide purity, high consumption, expensive catalysts, and high investment.
