  • Production of amines by hydrogenation of nitrile compounds
    Patent number: 8227642
    Abstract: A method for producing amines by the hydrogenation of nitrile compounds in the presence of a catalyst, notably a method for producing diamines by the continuous hydrogenation of dinitrile compounds in the presence of a Raney-metal catalyst, includes controlling the molar flow of nitrile compounds and the mass flow of catalyst in a hydrogenation piston reactor in order to minimize the occurrence of impurities and deterioration of the catalyst.
    Type: Grant
    Filed: September 13, 2007
    Date of Patent: July 24, 2012
    Inventors: Philippe Roccati, Didier Letourneur, Philippe Denis
