Abstract:
A reactor for an in-situ production of a chemical product in high yield are presented. The reactor, which may be placed in a main solvent, includes a core and a reactor wall around the core. The reactor wall allows controlled permeation of the main solvent to the core. The core contains a reactant that reacts to produce a target product upon being contacted by a main solvent. The target product leaves the reactor at a controlled rate. Because the amount of the main solvent that permeates into the reactor is controlled, a high concentration of the reactant is maintained inside the reactor, resulting in a higher yield of the desired chemical product than if the reactants were directly added to the body of main solvent.
Abstract:
A storable, stable composition that provides the effective antimicrobial benefits of halogenated agents is presented. The invention includes a water-soluble biocidal composition. The composition includes: about 0.01 to about 10 wt. % of a water-soluble inorganic halide; about 5 to about 60 wt. % of an oxidizing agent which, in aqueous solution, reacts with the inorganic halide to generate hypohalite ions; about 1 to about 15 wt. % of N-succinimide; and about 1 to about 30 wt. % of a pH buffering agent. The invention also includes a method of producing the above composition.
Abstract:
A product including potassium monopersulfate and a halogen is presented. The product is useful for treatment of aquatic facilities such as swimming pools. While it was known that using a combination of potassium monopersulfate and halogen is effective for sanitizing water, a product that includes both components could not be made because of the incompatibility between the two components. The product overcomes the incompatibility by use of a barrier film between the two components. The barrier film, which includes one or more of inorganic salt, silicate, borosilicate, and organic polymer, is coated onto one of the components prior to being combined with the second component. The product may be extruded and molded into a desired shape and added to the water to be treated, as needed.
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.
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 composition for providing an antimicrobial oxidizing agent is presented. The composition includes a core containing a reactant, and a reactor wall forming a reactor space that contains the core. The reactant generates an antimicrobial oxidizer product through a chemical reaction when contacted by a main solvent. The reactor wall has pores through which the main solvent enters the reactor space and the antimicrobial oxidizer product leaves the reactor space. The reactor wall has a lower solubility in the main solvent than the reactant and the oxidizer product and remains substantially intact during generation of the oxidizer product. A method of applying the antimicrobial composition and an animal litter composition that includes the antimicrobial composition are also presented.
Abstract:
A method of treating a peroxygen compound (e.g., potassium monopersulfate) for use in applications where controlled release rate, exposure to incompatible compounds, and/or moisture is presented. The method incorporates coating the peroxygen compound with one or more of the following polymers: 1) chitin/chitosan, 2) carboxylate/sulfonate copolymer or tertiary polymer, and 3) carboxylate polymer selected from polymaleic acid, polyepoxysuccinic acid and/or phosphinocarboxylate polymers. Optionally, the peroxygen compound is also coated with an inorganic salt layer and a silicate layer. Potassium monopersulfate coated with an organic polymer is useful in reduced allergenic formulations and as an anti-caking agent. When the organic polymer is a polysaccharide, the coated potassium monopersulfate is also effective for shock treatment of water systems (e.g., pools). The oxidizing composition prepared with this method has a prolonged shelf life while demonstrating good solubility during use.
