  • Mixtures for producing chlorine dioxide gas in enclosures and methods of making the same
    Patent number: 9382116
    Abstract: The present disclosure relates to a mixture for producing chlorine dioxide gas provided in an enclosure comprising an impregnate comprising a chlorine dioxide precursor impregnated in a porous carrier and a proton-generating species, wherein the impregnate and proton-generating species are intermixed to produce a stable mixture and the mixture is provided in an enclosure. The present disclosure also relates to methods for producing chlorine dioxide gas.
    Type: Grant

  • Process for the production of chlorine dioxide
    Patent number: 5545389
    Abstract: A process for the production of chlorine dioxide by reacting at least one of chloric acid and an alkali metal chlorate, and hydrogen peroxide as the reducing agent in such proportions that chlorine dioxide is produced in a reaction medium. A mixture comprising chlorine dioxide and oxygen is withdrawn from the reaction medium. Urea and/or one or more phosphonic acid based complexing agents are added to the reaction medium. The stabilizer is added in an amount of 0.01-5 weight % and serves to increase the reaction rate.

  • Method of producing chlorine dioxide
    Patent number: 5486344
    Abstract: The invention relates to a method of producing chlorine dioxide, which method comprises reacting chloric acid with hydrogen peroxide as a reducing agent in such proportions that chlorine dioxide is produced.

  • Plug flow process for the production of chlorine dioxide
    Patent number: 5376350
    Abstract: A plug flow process for the production of chlorine dioxide by reacting chloric acid and/or an alkali metal chlorate, optionally a mineral acid and a reducing agent in such proportions that chlorine dioxide is produced. Reactants are continuously fed to a plug flow reactor under conditions that chloride dioxide is produced as the reactants flow through the reactor. The process stream has an acidity between 2N and 11N. The process stream is subjected to superatmospheric pressure in the reactor sufficient to maintain the formed chlorine dioxide in solution. After removal of the chlorine dioxide from the process stream exiting the plug flow reactor, the process stream can optionally be fed to a second chlorine dioxide generator for further reaction.
