Copper chromite catalysts were prepared by using a new metal organic precursor, M(OR)n, which was dissolved in organic solvent,
hydrolysed and condensed to form inorganic polymers containing M-O-M linkages. In the cases of Ba and Mn promotion, the corresponding
metal oxide was admixed to the copper-chromium solution prior to gelification. After drying in helium atmosphere, the precursor
was subjected to thermal treatment at different temperatures (373-873 K) and in different atmospheres (air, nitrogen or hydrogen).
Both the catalysts and the industrial Engelhard catalyst were characterized by various techniques (TG-DTA, HTXRD, IR, BET,
metallic copper surface area and porosimetry measurements) and evaluated for ester hydrogenation.
