Abstract: Prodn. of arylamines of formula (I) comprises (a) preparing a cycloalkylamine of formula (II) by the hydrogenative amination of a phenol (III) with NH3/H2 at 100-250 deg.C under 0.01-50 bar pressure in the presence of catalyst (A); and (b) dehydrogenation of (II) at 150-300 deg.C under 0.01-50 bar pressure in the presence of a catalyst (A). (A) comprises: 30-100 wt.% of a Pd component (A1) and 0-70 wt.% alkali- and/or alkaline earth oxide. (A1) comprises Pd (opt. mixed with Pt) on oxides of rare earth and/or Group IVb; or Pt/Pd mixts. on Al2O3. R1-R5 = H, 1-12C alkyl or 3-12C cycloalkyl. Step (b) is independently claimed.
