  • Patent number: 8648026
    Abstract: A composition for dissolving and/or inhibiting deposition of scale on a surface of a system comprises an acidic component, a wetting agent, and a corrosion inhibitor. The composition may further comprise water. The acidic component comprises an alkanesulfonic acid, e.g. methanesulfonic acid (MSA). The wetting agent comprises a surfactant. The corrosion inhibitor comprises an amphoteric surfactant. The alkanesulfonic acid is present in an amount of at least about 50 weight percent (wt %), the surfactant is present in an amount of from about 0.1 to about 30 wt %, and the amphoteric surfactant is present in an amount of from about 0.025 to about 20 wt %, each based on 100 wt % of the alkanesulfonic acid, the surfactant, and the amphoteric surfactant combined. A method of dissolving and/or inhibiting deposition of scale on the surface of the system comprises the step of contacting the surface of the system with the composition.

  • Publication number: 20130017241
    Abstract: An encapsulated chlorine dioxide generator is provided. The encapsulated generator includes a core particle that includes a metal chlorite and a solid acid. The encapsulated generator also includes a protective layer that is disposed about at least a portion of the core particle. The protective layer includes a copolymer of polyvinyl alcohol and a polyalkylene glycol. The encapsulated generator is formed in a method including the steps of forming the core particle and disposing the protective layer about the core particle. The encapsulated generator is also used in a method of cleaning an environment. The method of cleaning the environment includes the steps of providing the encapsulated generator and forming chlorine dioxide from the encapsulated chlorine dioxide generator to clean the environment.

  • Publication number: 20110049053
    Abstract: A method of inhibiting the deposition of silica and/or silicate compounds on a surface in an aqueous system is provided. The method comprises the step of adding a polymer to the aqueous system. The polymer comprises at least one constitutional unit (i) and at least one additional constitutional unit (ii). The constitutional unit (i) is represented by the formula: wherein R is an alkyl group having at least 2 carbon atoms; R1 is selected from the group of a hydrogen atom, an alkyl group, an aryl group, an ester, an amide, and an imide; k is 2 to 4; and n is at least about 10. The additional constitutional unit (ii) contains at least one group selected from the group of carbonyl groups, sulfonate groups, and phosphate groups.
