  • PROCESS FOR THE PRODUCTION OF ETHER ISOCYANATES BACKGROUND OF THE INVENTION
    Publication number: 20020045723
    Abstract: Ether isocyanates are prepared by phosgenation of ether amines in the vapor phase.
    Type: Application
    Filed: September 13, 1996
    Publication date: April 18, 2002
    Inventors: FRANK RICHTER, JOSEF PEDAIN, KLAUS KACHTKAMP, ANDREAS FLINK
  • Process for the phosgenation of amines in the gas phase using microstructure mixers
    Patent number: 6225497
    Abstract: A process for rapidly mixing phosgene and an amine in the gas phase to produce the corresponding isocyanate. Micro-structure mixers are used for the rapid mixing. The educts emerge from the micro-structure mixer in the form of thin free jets which mix very rapidly by diffusion and/or turbulence. As a result, the mixing operation is accelerated substantially as compared with conventional reactors. The isocyanate yield is also increased.

  • Process for preparing triisocyanates
    Patent number: 5633396
    Abstract: Triisocyanates are produced by gas phase phosgenation of the corresponding (cyclo)aliphatic triamines having three primary amine groups.
    Type: Grant
    Filed: June 17, 1996
    Date of Patent: May 27, 1997
    Assignee: Bayer Aktiengesellschaft
    Inventors: Eric Bischof, J urgen Dahmer, Andreas Flink, Wolfgang Krohn, Attila Molnar
  • Process for the production of diisocyanates
    Patent number: 5516935
    Abstract: Diisocyanates are produced by gas-phase phosgenation of aliphatic diamines having two primary amino groups in the 1,2- or 1,3-position to one another or by cycloaliphatic diamines having two primary amino groups in the 1,2- or 1,3-position to one another.
    Type: Grant
