ABSTRACT:
An unreduced catalyst which contains, per 100 parts by weight of CuO, 40 to 130 parts by weight of ZnO, 2 to 50 parts by weight of Al.sub.2 O.sub.3 and, optionally, 0.5 to 8 parts by weight of an oxide of Mn, Mo, V, Zr and/or an alkaline earth metal, and, also optionally, 2 to 80 parts by weight of a support. The catalyst has a total BET surface area of 80 to 175 m.sup.2 /g, 75% to 95% of the total BET surface area is formed by pores having a radius r.sub.p .ltoreq.15 nm. The invention further relates to a process for the production of the catalyst and its use for the hydrogenation of aldehydes.
