Pref. the catalyst is a heterogeneous one and contains at least one group Ib, VIIb or VIIIb metal, pref. one or more from Co, Cu, Mn, Mo, Na, NI, Re, Os or Ru, most pref. Co, Ni, Cu or Re. The catalyst carrier is chosen from one or more of the following: oxides of Al and Ti, ZrO2, SiO2, diatomaceous earth, silica gel, alumina, silicates, zeolites or active carbon. Hydrogenation is carried out at 0-300 (60-220) degrees C and 1-300 (10-250) bar in a solvent.
