Highly selective hydrogenation of dimethyl oxalate to methyl glycolate and ethylene glycol over an amino-assisted Ru-based catalyst

A Ru/NH 2 -MCM-41 catalyst was prepared via a coordination-assisted strategy for chemoselective hydrogenation of dimethyl oxalate with a high selectivity of methyl glycolate ( ca. 100%) and ethylene glycol (>90%) at reaction temperatures of 343 K and 433 K, respectively. The amino groups help to...

Description
Summary:A Ru/NH 2 -MCM-41 catalyst was prepared via a coordination-assisted strategy for chemoselective hydrogenation of dimethyl oxalate with a high selectivity of methyl glycolate ( ca. 100%) and ethylene glycol (>90%) at reaction temperatures of 343 K and 433 K, respectively. The amino groups help to anchor and form stable electron-rich Ru active sites, which accounts for the excellent C&z.dbd;O bond activation and hydrogenation selectivity. A Ru/NH 2 -MCM-41 catalyst was prepared via a coordination-assisted strategy for highly chemoselective hydrogenation of dimethyl oxalate to methyl glycolate ( ca. 100%) and ethylene glycol (>90%) at low reaction temperature (343-433 K).
