Hydrogenation of dimethyl oxalate to ethylene glycol is one of the key steps in the technology of glycol synthesis from syngas. The selective hydrogenation of dimethyl oxalate to methyl glycolate and ethanol is introduced briefly. The research progress of selective hydrogenation of dimethylsilyl oxalate to methyl glycolate, ethylene glycol and ethanol was summarized. The influence of non-silicon carrier species and additives and preparation methods were analyzed. The effects of DMO selectivity plus Problems and development of hydrogen-non-silicon catalyst system.
