Abstrakt: Summary 1.A zinc-copper catalyst selectively catalyzes the hydrogenation of the C=O bond in mesityl oxide, while remaining inert for the hydrogenation of the C=C bond. On the other hand, over a copper catalyst hydrogen adds primarily at the C=C bond. Over a copper catalyst 4-methyl-3-penten-2-ol is not isomerized at 125°.2.The selectivity of a zinc-copper catalyst is determined by its zinc component, and its lower activity, as compared with a zinc catalyst, for the isomerization of the unsaturated alcohol into the saturated ketone is due to the presence of copper in the catalyst.
