Abstract
A process for the preparation of a compound comprising precipitation from an aqueous solution of a mixture of nickel, aluminum, and zirconium salts by means of an aqueous precipitating solution. The latter contains an amount of a basic compound which is in stoichiometric excess of that required for complete precipitation of the salts. The precipitation is carried out at at least 60.degree. C. and a pH of 7 to 10. A catalyst which is the product of the foregoing process, as well as its use in the hydrogenation of nitriles, aromatic hydrocarbons, nitro compounds, and/or olefins is also disclosed.
