  • Process for removing NO and NO from gas mixtures
    Patent number: 8894960
    Abstract: A process is proposed for reprocessing the exhaust gas from a plant for producing hydroxylamine or hydroxylammonium salts by catalytic reduction of nitrogen monoxide with hydrogen for the purpose of utilization of at least a part of the nitrogen monoxide and if appropriate hydrogen present in the exhaust gas for producing hydroxylamine or hydroxylammonium salts, which comprises, in a first separation stage, selectively separating off nitrogen monoxide from the exhaust gas of the plant for producing hydroxylamine or hydroxylammonium salts.
    Type: Grant
    Filed: November 30, 2007
    Date of Patent: November 25, 2014
    Assignee: BASF SE
    Inventors: Carsten Oost, Wolfgang Rohde, Christian Miller, Manfred Stroezel, Alfred Thome, Wilfried Berning
  • METHOD FOR THE OXIDATION OF CYCLOALIPHATIC ALCOHOLS, CYCLOALIPHATIC KETONES, OR MIXTURES THEREOF WITH AQUEOUS NITRIC ACID AND TREATMENT OF THE DICARBOXYLIC ACIDS
    Publication number: 20100249452
    Abstract: A process for preparing dicarboxylic acids by oxidizing cycloaliphatic alcohols, cycloaliphatic ketones or mixtures thereof with nitric acid, by performing the reaction and separation of the components in a fractionating column or rectification column.

  • Oxidation method
    Publication number: 20050288532
    Abstract: A process for oxidizing a starting material with an oxidizing agent to obtain a product, which comprises carrying out the oxidation in a reaction apparatus which has a bottom region at the lower end, a top region at the upper end and a reaction zone between the top region and the bottom region, maintaining the reaction mixture in the boiling state in the reaction zone, and introducing oxidizing agent into the reaction zone in at least two substreams.
