  • Patent number: 6660307
    Abstract: Active bromine-containing solutions are produced and stabilized by reacting bromate and bromide salt solutions with an amino-complexing agent, such as sulfamic acid or sulfamate salt. The reaction is performed at a pH of less than 1 to create a complexed hypobromate. The pH of the active bromine-containing solution is raised to between 4 and 10 by adding an alkali to improve stability. Moreover, the solution is maintained below 30° C. during the alkali addition to retain bromine equivalent activity.

  • Patent number: 6652889
    Abstract: Described is a process of producing a concentrated liquid biocide formulation. Mixed together are (a) bromine chloride or bromine and (b) an aqueous solution of alkali metal salt of sulfamic acid having a pH of at least about 7, in amounts such that (i) the active bromine content of the solution is at least about 100,000 ppm (wt/wt), and (ii) the atom ratio of nitrogen to active bromine from (a) and (b) is greater than 1 when bromine is used and is greater than 0.93 when bromine chloride is used. Use of bromine chloride as the source of the active bromine in the process is preferred because in the resulting aqueous compositions, all of the bromine of the bromine chloride is made available as active bromine in solution. In other words, the chlorine of the bromine chloride is converted in the process to dissolved alkali metal chloride salt, thereby liberating all of the bromine in the biocidal composition as active bromine capable of providing biocidal activity.

  • Patent number: 6471974
    Abstract: The antimicrobial efficacy of N-chlorosulfamate solutions, namely buffered aqueous combinations of HClNSO3−(mono-N-chlorosulfamate) and Cl2NSO3 (di-N-chlorosulfamate), herein referred to as “stabilized hypochlorite”, can be markedly enhanced by the addition of certain organic dopants. The dopants themselves are select hypochlorite stabilizing agents, which are known to readily form stable organochloramides when reacted with “free” hypochlorite (HOCl or NaOCl). Highly effective antimicrobial enhancing dopants include 5,5-dialkyl hydantoins, arylsulfonamides, and succinimides. Examples of these include 5,5-dimethylhydantoin, benzenesulfonamide, and succinimide. Other, less effective dopants include glycolurils. Generally, the dopant is present in a minor mole fraction, relative to the molar amount of stabilized hypochlorite present in the enhanced antimicrobial solution.

  • Patent number: 6106853
    Abstract: Processes for controlling pollution by: (a) devolatizing vapor phase chemical pollutants (VP's) found in effluents and other bodies and streams of gases and liquids, and (b) stabilizing substrates from which the VP's are released. The offending VP's are converted to less offensive or inoffensive materials by interaction with an appropriately formulated treating agent (VTA/C) containing a primary halogen and at least one additional ingredient selected from the following classes of constituents (optional if bromine is the primary halogen and otherwise required): oligodynamically active metals, cohalogens, adjuncts, and facilitators. The major constituent(s) may be supplied as such, or a source of the constituent may be provided. Actinic radiation can be employed to promote reactions between the VP and the VTA/C, which is often formulated as an aqueous scrubbing medium.

  • Patent number: 6068861
    Abstract: Described is a process of producing a concentrated liquid biocide formulation. Mixed together are (a) bromine chloride or bromine and (b) an aqueous solution of alkali metal salt of sulfamic acid having a pH of at least about 7, in amounts such that (i) the active bromine content of the solution is at least about 100,000 ppm (wt/wt), and (ii) the atom ratio of nitrogen to active bromine from (a) and (b) is greater than 1 when bromine is used and is greater than 0.93 when bromine chloride is used. Use of bromine chloride as the source of the active bromine in the process is preferred because in the resulting aqueous compositions, all of the bromine of the bromine chloride is made available as active bromine in solution. In other words, the chlorine of the bromine chloride is converted in the process to dissolved alkali metal chloride salt, thereby liberating all of the bromine as the active bromine content of the biocidal composition.

  • Patent number: 5993864
    Abstract: A novel chelate complex allows the formation of stable solutions of molecular chlorine dioxide. The chelate complexes are composed of the electron-deficient chlorine dioxide molecule, which can accept an electron, and a chelating agent, which can contribute its available electrons to the accepting orbital of the chlorine dioxide molecule. Both active and passive methods of releasing the chlorine dioxide from such chelates by competitive displacement with selected metal cations are presented. In this manner a stabilized solution of molecular chlorine dioxide can be stored until needed and the chlorine dioxide released at time of use for cleaning, disinfection or other uses.
