설명

일반 설명

Dimethyl oxalate undergoes Cu/SiO₂ catalyzed hydrogenation to yield ethylene glycol. It undergoes selective gas-phase hydrogenation catalyzed by Ag/SiO₂ to yield corresponding alcohol.

애플리케이션

Dimethyl oxalate (DMO) was used as alternate fuel in direct oxidation fuel cell. DMO was used to study the IR spectra of DMO isolated in noble gas low-temperature matrices.
