Soluble in ethanol. Slightly soluble in water.

용도

Dimethyl oxalate is used as an alternate fuel in the direct oxidation fuel cell. It is involved in the catalytic hydrogenation using Cu/SiO2 to prepare ethylene glycol. It is also used in the selective gas-phase hydrogenation catalyzed by Ag/SiO2 to get the corresponding alcohol.

참고

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