Abstract

The hydrogenation of 3-penten-2-one on well-defined SiO2 supported Ni, Cu, Ru, Rh, Pd and Pt catalysts has been investigated under the same experimental conditions. Reactions were performed in the liquid phase in methanol at 298 K and in the gas phase at 393 and 473 K. On the basis of the turnover yields, the activity of metals was found to decrease in the order Pt>Pd≥Rh≫Ru>Ni>Cu. Selective hydrogenation of the olefinic double bond of 3-penten-2-one resulted in the formation of 2-pentanone which was further hydrogenated to 2-pentanol on all catalysts, except on Pd/SiO2.
