Abstract: The effect of the second metal (Pt, Pd, Ni and Fe) on the activity of copper phyllosilicate-based catalysts was investigated in the selective hydrogenation of dimethyl oxalate to ethylene glycol at 160–200 °C. The prepared catalysts were characterized by XRD, DRIFTS-CO and TEM methods. The conversion achieved over 10Fe/10Cu-PhySi catalyst was 68 % at 200 °C; at the same time, the full conversion with selectivity 98% was obtained at the temperature of 180 °C over a bimetallic 1Pt/Cu-PhySi catalyst.

Keywords: dimethyl oxalate, ethylene glycol, ester hydrogenation, copper phyllosilicate, bimetallic catalyst, copper catalyst.
