ABSTRACT:
A low-pressure process for the hydrogenation of aromatic amines to give the corresponding symmetrical dicycloaliphatic amines in the presence of rhodium catalysts which are unmodified or modified by Ir, Ru, Os, Pd and/or Pt or mixtures of these metals, on supports modified by oxides of Cr, Mo, W, Mn and/or Re or mixtures of these oxides.
