Abstract
The present invention is concerned with a process for the catalytic hydrogenation of organic compounds on a catalyst of amorphous metal alloys and in a solvent, with the hydrogenation being carried out under near-critical or supercritical conditions of the solvent. The amorphous metal alloys can be produced by the shock cooling of alloy melts having eutectic solidification points. By hydrogenation at hydrogen partial pressures between 5 and 400 bar there is obtained outstanding space-time yields with high long-term stability of the catalytic activity.
