Abstract
The preparation and application of a 5% Pt/K-10 catalyst is described. The catalyst was found to be highly selective in the hydrogenation of cinnamaldehyde with almost exclusive formation of cinnamyl alcohol. T he unsaturated alcohol was formed with selectivities up to 99% during cinnamaldehyde hydrogenation under mild experimental conditions (25 de grees C, 4 bar). The beneficial role of a significant support effect w as interpreted to be due to the Lewis acid centers of the support, whi ch provide suitable anchoring sites for C=O moieties.
