Abstract

Abstract : A Ru/NH2 -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). Abstract : A Ru/NH2 -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O bond activation and hydrogenation selectivity.
