Abstract: A process for continuously preparing a primary aromatic amine by reacting a corresponding cycloaliphatic alcohol with ammonia in the presence of hydrogen at a temperature in the range from 80 to 350° C. in the presence of a heterogeneous catalyst, wherein the catalytically active composition of the catalyst, before its reduction with hydrogen, comprises from 90 to 99.8% by weight of zirconium dioxide (ZrO2), from 0.1 to 5.0% by weight of oxygen compounds of palladium and from 0.1 to 5.0% by weight of oxygen compounds of platinum.

Abstract: Processes comprising: providing an aromatic alcohol; and reacting the aromatic alcohol with ammonia at a temperature of 80 to 350° C. in the presence of hydrogen and a heterogeneous catalyst to form a crude reaction product comprising a corresponding primary aromatic amine, wherein the heterogeneous catalyst comprises a catalytically active composition which, prior to reduction with hydrogen, comprises 90 to 99.8% by weight of zirconium dioxide (ZrO2), 0.1 to 5.0% by weight of an oxygen-comprising compound of palladium, and 0.1 to 5.0% by weight of an oxygen-comprising compound of platinum.

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.
