Abstract The gas phase hydrogenation of acrolein, 2-methyl-2-propenal, 2-butenal and 3-methyl-2-butenal was studied on Ru/Al2O3 and RuM/Al2O3 catalysts (M=Sn, Fe, Zn, Ge, Sb). The specific activity increases when the second element is added to the parent Ru/Al2O3 catalyst. This was ascribed to the activation of the C=O bond by Mδ+ species. Tin is the only additive which promotes the allyl alcohol selectivity. When methyl groups are tagged on the C=C bond the selectivity to the unsaturated alcohol increased sharply due to the steric hindrance against the adsorption of the substrate via the C=C double bond.
