The hydrogenation of acetone adsorbed and the dehydrogenation of isopropanol adsorbed on silica-supported nickel catalyst have been studied by following the changes of hydrogen pressure and the reaction products as well as the IR spectra of adsorbed species. It was found that the formation of isopropanol proceeds <I>via</I> a precursor composed of acetone and hydrogen. The activation energies of hydrogenation of acetone adsorbed and of dehydrogenation of isopropanol adsorbed were 11–13 and 4–8 kcal/mol, respectively. The activation energy of the desorption was 13 kcal/mol for isopropanol and 19 kcal/mol for acetone. From the results the potential energy change during the hydrogenation of acetone was determined.
