Abstract
A 2-alkylphenol is prepared by reduction of a 2-acylphenol in the presence of a metallic catalyst. The reaction is carried out at a temperature of 80.degree. to 200.degree. C. and under a pressure of 10 to 100 bars, and a base metal, in particular copper, is used as a catalyst. It is particularly advantageous to use the catalyst in combination with a support. The hydrogenation of the acylphenol is advantageously carried out in the presence of an inert solvent. The process can be carried out continuously or discontinuously. The alkylphenols obtained are suitable for use in the synthesis of active substances having biocidal properties.
