  • Method for the continuous production of an amine
    Patent number: 7767855
    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.
    Type: Grant
    Filed: June 21, 2006
    Date of Patent: August 3, 2010
    Assignee: BASF SE
    Inventors: Frank Haese, Joachim Wulff-Doering, Ulrich Koehler, Peter Gaa, Frank-Friedrich Pape, Johann-Peter Melder, Manfred Julius
  • PROCESS FOR CONTINUOUS PREPARATION OF A PRIMARY AROMATIC AMINE
    Publication number: 20090076306
    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.
