ABSTRACT:
An improved process for catalytic hydrogenation of aromatic carboxylic acids to produce aromatic aldehydes is described, using a catalyst comprising zirconium oxide containing as an essential component at least one element selected from the group consisting of chromium, manganese, iron, cobalt, zinc, bismuth, lead, rhenium and the elements of Group III of periods 3 to 6 of the periodic table; the process results in improved catalyst activity and produces the desired aromatic aldehydes in high yield.
