Patent number: 7465411Abstract: A composition capable of expedited in-situ generation of dioxirane and a method of preparing the composition are presented. The composition includes a transition metal catalyst, peracid donor, and carbonyl donor, and forms an effective multi-purpose oxidizing (e.g., bleaching) solution. Methods of using the bleaching solutions and their application are also presented. The composition provides a cost-effective means of producing a dioxirane-based multi-purpose bleaching solution for use on laundries, carpets, hard surfaces, bathroom surfaces, floors and the like.Type: GrantFiled: March 16, 2006Date of Patent: December 16, 2008Assignee: Truox, Inc.Inventor: Roy W.

Patent number: 7465410Abstract: 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.Type: GrantFiled: February 18, 2005Date of Patent: December 16, 2008Assignee: Truox, Inc.Inventors: Perry L. Martin, Roy W. Martin

Patent number: RE41109Abstract: A composition of matter and the method of making that provides a low pH acidic composition that is useful for destroying microorganisms that are undesirable and useful for destroying or reducing melanomas on human skin. The composition and method include sulfuric acid combined with distilled water and ammonium sulfate under at least 15 psi pressure in a pressurized container, all of which is heated to approximately 800° F. or more for at least 3 hours. The final cooled mixture is stabilized with 10 percent of the original mixture. The resultant composition is useful for preserving food, such as fresh fish, and for skin treatment of melanoma and as bactericides, fungicides, or viricides.Type: GrantFiled: June 3, 2003Date of Patent: February 9, 2010Assignee: Phitex, L.L.L.P.Inventor: Barry W.
