  • STORAGE-STABLE AQUEOUS SOLUTIONS OF CHLORINE DIOXIDE AND METHODS FOR PREPARING AND USING THEM
    Publication number: 20100209528
    Abstract: The present invention is for extremely pure solutions of chlorine dioxide, methods for making such solutions and to compositions and methods for storing, shipping and using such solutions. Generally, the chlorine dioxide solutions of the invention are aqueous solutions containing about 2500 ppm or less of total impurities. The chlorine dioxide solution can be prepared by passing dilute highly pure chlorine gas through a bed of substantially solid sodium chlorite and contacting the resulting chlorine dioxide gas with a liquid.

  • USE OF STORAGE-STABLE AQUEOUS SOLUTIONS OF CHLORINE DIOXIDE TO GENERATE PURE CHLORINE DIOXIDE GAS FOR DECONTAMINATION
    Publication number: 20090142226
    Abstract: New compositions and methods are disclosed for decontaminating surfaces and enclosures that avoid problems such as salt deposits, corrosion and condensation that accompany the use of known methods. The process involves the use of chlorine dioxide solutions prepared by passing dilute chlorine gas over solid granular sodium chlorite to produce chlorine dioxide gas which is then collected in solution. The chlorine dioxide gas can be introduced into an enclosure and used to disinfect a portion of the contents of the enclosure.

  • Method and Apparatus for Generating Gaseous Chlorine Dioxide-Chlorine Mixtures
    Publication number: 20070183961
    Abstract: Gaseous mixture of chlorine dioxide and chlorine produced by reacting an inorganic acid with an aqueous solution of an alkali metal chlorate by controlled introduction of the inorganic acid into the aqueous solution of alkali metal chlorate. Inorganic acid passed through a volume of alkali metal chlorate flowing through a horizontal reactor in a plug flow regime results in an enhanced gaseous mixture of chlorine dioxide, chlorine and steam that can be withdrawn as a product stream.
