- Aliphatic acids such as butyric acid and hexanoic acid were hydrogenated over a commercial
CuO/ZnO/Al2O3 catalyst. The liquid-phase reaction was conducted in a fixed-bed reactor by varying the
pressure of hydrogen and the molar ratio of acid to water. Over copper-containing catalysts, the major
products, that is, alcohols as well as ester byproducts were formed directly from aliphatic acids, where the
hydrogenation of acids, the esterfication of acids with alcohols and the hydrogenolysis of esters occur
concurrently. It was found that the selectivities of alcohols and esters were influenced by not only the
presence of water in the liquid phase but the H2 pressure.
