ABSTRACT

Cu-M-Cr catalysts (M= Cu, Zn, and Co), which are very active in the hydrogenation of crude oxoaldehyde mixtures, may be obtained by the reduction of non-stoichiometric spinel-type compounds containing an excess of divalent cations, These catalysts do not require physical or chemical promoters, while also exhibiting a higher activity than that of commercial catalysts and, furthermore, a higher stability towards by-products.
