Abstract: An improved oxidizing composition and a method of preparing it are presented. The improved oxidizing composition includes a solvent-activated reactor and a halogen component. The solvent-activated reactor generates one or more preselected oxidizing products when contacted by a main solvent. The halogen component is also added to the main solvent and synergistically performs oxidation. The oxidizing composition may be used to treat bodies of water such as pool and spa and to bleach materials. Some examples of the halogen component include calcium hypochlorite, trichloroisocyanurate, dichloroisocyanurate, lithium hypochlorite, dibromo-dimethylhydantoin, bromo-chloro-dimethylhydantoin, sodium bromide, sodium chloride, and a combination thereof.

Abstract: A method and apparatus for production of a high-concentration H2SO5 solution is presented. This high-concentration H2SO5 solution is useful for producing a stable, non-hygroscopic triple salt. The invention includes a single-stage reactor that includes a reservoir for holding an oxyacid solution and an inlet to the reservoir for receiving a peroxide solution. The peroxide solution is added such that a gradient of peroxide concentration forms in the oxyacid solution as a function of distance from the inlet, and less than all of the oxyacid solution reacts with the peroxide solution at a given time. A stirring mechanism slowly dissipates the gradient, so that any H2SO5 formed as a result of reaction between the peroxide and the oxyacid is stirred away from the high-peroxide concentration zone, thereby preventing the decomposition of H2SO5 by an equilibrium reaction. The temperature of the reservoir is maintained at less than or equal to 20 ° C.

Abstract: A stable oxidizing composition and a method of preparing such composition are presented. The composition includes a peroxygen (e.g., potassium monopersulfate, percarbonate) particle suspended in an alcoholic gel. The alcohol content in the gel prevents the peroxygen particle from coming into contact with water during storage, thereby helping maintain a high available oxygen level. When the alcoholic gel is mixed with water, it becomes less viscous and exposes the peroxygen particle to the water. The peroxygen is ready for use when it dissolves in the water. Other additives may also be suspended in the alcoholic gel for storage. The composition is prepared by first preparing an alcoholic gel, then suspending a peroxygen particle in the alcoholic gel. The alcoholic gel is prepared by combining an alcohol with a polymer.
