Applications

Dimethyl oxalate is used as an alternate fuel in the direct oxidation fuel cell. It is involved in the catalytic hydrogenation using Cu/SiO<sub>2</2ub> to prepare ethylene glycol. It is also used in the selective gas-phase hydrogenation catalyzed by Ag/SiO<sub>2</sub> to get the corresponding alcohol.

Notes

Moisture sensitive. Incompatible with strong oxidizing agents, acids, bases and reducing agents.
