  • Process for producing aromatic amines
    Patent number: 9067864
    Abstract: Aromatic amines are produced by adiabatic hydrogenation of nitroaromatic compounds in the gas phase on one or more fixed catalysts. The nitroaromatic reactant is passed over the catalyst under pressure and at elevated temperature with hydrogen, water, optionally nitrogen and substantially in the absence of the aromatic amine produced from the nitroaromatic.
    Type: Grant
    Filed: July 25, 2007
    Date of Patent: June 30, 2015
    Assignee: Bayer MaterialScience AG
    Inventors: Knut Sommer, Ido Schwarz, Susanne Buchholz, Franz-Ulrich Von Gehlen, Andre Lago, Karl-Heinz Wilke, Holger Orzesek, Hans-Georg Pirkl, Peter Lehner, Stephan Schubert
  • Process for removing compounds containing phenolic hydroxy groups from aromatic amines
    Patent number: 7488850
    Abstract: Compounds containing phenolic hydroxy groups are removed from a gas stream which contains at least one aromatic amine generated during the gas-phase hydrogenation reaction of the corresponding nitroaromatic compounds with hydrogen, by adsorption on a basic solid.
    Type: Grant
    Filed: November 6, 2007
    Date of Patent: February 10, 2009
    Assignee: Bayer MaterialScience LLC
    Inventors: Knut Sommer, Markus Dugal, Ido Schwarz, Stefan Wershofen, Peter Lehner, Stephan Schubert, Alexandra Groβe Böwing
