General description
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.
Application
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.

Ag/SiO(2) prepared by a sol-gel process is highly effective for selective gas-phase hydrogenation of dimethyl oxalate to corresponding alcohols. The catalysts are of great potential as industrially viable and novel catalysts for the production of methyl glycolate and ethylene glycol.

The variation of the supports on the Cu/SiO2 catalyst plays an important role in the catalytic performance for hydrogenation of dimethyl oxalate. The loss of silica in the form of tetramethoxysilane from the support under the reaction conditions is responsible
