Patent number: 6225497Abstract: 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.Type: GrantFiled: January 6, 1999Date of Patent: May 1, 2001Assignees: Bayer Aktiengesellschaft, Forschungszentrum Karlsruhe GmbHInventors: Gernot Becker, Konrad Fischer, Andreas Flink, Erhard Herrmann, Lothar Weismantel, Georg Wiessmeier, Klaus Schubert, Maximillian Fichtner
