  • Method and system for producing nitrobenzene
    Patent number: 9139508
    Abstract: The present invention relates to a process and a plant for the production, in particular the continuous production, of nitrobenzene by means of adiabatic nitration of benzene with nitric acid in the presence of sulfuric acid, in which, following the nitration, a multi-stage concentration of the sulfuric acid is carried out by means of heating at a pressure that is reduced as compared with ambient pressure, and wherein the heating takes place using the heat generated in the adiabatic nitration of benzene.
    Type: Grant
    Filed: January 28, 2013
    Date of Patent: September 22, 2015
    Assignee: Bayer Intellectual Property GmbH
    Inventors: Bernd Pennemann, Juergen Munnig, Wulf Dietrich, Andreas Karl Rausch
