Abstract

In a process for the preparation of cyclohexane carboxylic acid by the hydrogenation of benzoic acid at a temperature between 140 DEG and 200 DEG C. in the presence of catalysts containing nickel and silicon dioxide, the hydrogenation is carried out with catalysts produced from nickel salt solutions which contain suspended silica gel, by precipitation with alkali hydroxide, filtration, washing, drying and subsequent reduction at temperatures of between 220 DEG and 400 DEG C. The hydrogenation may be carried out without pressure and in the vapour phase or in the liquid phase at a pressure of 40-220 atmospheres or in a solvent such as cyclohexane carboxylic acid or cyclohexane carboxylic acid ester. Examples are described.
