  • Process for the production of aqueous chlorine dioxide solutions
    Patent number: 6103950
    Abstract: The description relates to a process for the production of aqueous chlorine dioxide solutions through oxidation of chlorite with oxo acids and/or oxo acid anions having a suitable redox potential in a buffered aqueous medium, wherein an acidic aqueous solution A is produced which has a pH of about 5 or less and contains the oxo acids and/or oxo acid anions, and the acidic aqueous solution A is mixed with an aqueous chlorite solution B to form chlorine dioxide, wherein a pH of less than 6.95 is adjusted in the reaction mixture, this pH value being stabilized by a buffering system contained therein.
    Type: Grant
    Filed: August 23, 1999
    Date of Patent: August 15, 2000
    Inventors: Manfred Rimpler, Fritz Kueke, Marcus Rimpler
