  • Patent number: 8722881
    Abstract: A tetradendate amide based macrocyclic ligand and its Fe(III) complex which act as activators of hydrogen peroxide. The synthetic methodology to develop the ligands is new, simple and provides better yield for each step of the ligand synthesis. The Fe(III)-complexes and hydrogen peroxide together are can perform several environmentally benign oxidation reactions. Organic dye bleaching, bleaching of pulp and paper effluent and N-oxide synthesis may be performed using the newly developed catalyst and hydrogen peroxide. Alcohol oxidation and alkene epoxidation may also be performed using the catalysts and hydrogen peroxide.

  • Patent number: 7976725
    Abstract: An efficient cyclic process and related compositions for the in-situ generation of chlorine dioxide from dilute solutions of chlorite anions at near neutral pH. The cyclic process provides a means of safe and effective use of chlorine dioxide with reduced concern of chlorite accumulation in the aqueous system. The disclosed chemistry used to support the cyclic process can be applied independently or in various combinations that are effectively inert. This dramatically reduces safety concerns since the chlorine dioxide is produced in-situ to the application and in dilute concentrations. Also, the process allows for regeneration of inert anions such as bromide and chlorite thereby reducing operating cost.

  • Patent number: 7695631
    Abstract: A method and composition for reducing chemical oxygen demand is presented. The composition includes a persulfate donor and a transition metal catalyst in contact with the persulfate donor. When the composition is contacted by water, the transition metal catalyst reacts with persulfate and reduces the persulfate concentration in the water. The composition allows the use of persulfate, which is known to cause irritation to users of aquatic facilities (e.g., pools, spas) that come in contact with it. As the persulfate concentration is reduced rapidly in the water by the catalyzed reaction, the persulfate-containing cleaning product may even be used while the aquatic facilities are being used. Optionally, a free halogen donor may be incorporated into the composition. The composition may be in the form of powder, granules (coated or uncoated), or agglomerate.

  • Patent number: 7238290
    Abstract: Transition metal ions have the ability to increase the oxidation performance of the inorganic peroxy salts at room temperature by possibly lowering their activation energy or by producing more reactive free radicals. When two transition metal salts are used together to decompose dipersulfate, it provides synergistic oxidation activity, better than obtained by dipersulfate or dipersulfate with either copper or zinc alone. The transition metals mentioned are the water soluble salts of copper and zinc. Oxidation performance of sodium dipersulface in presence of catalytic amount of copper and zinc salts was determined by measuring the destruction of crystal violet dye at a wavelength of 589 nm.

  • Publication number: 20030160209
    Abstract: Formation of solid-water detoxifying reagents for chemical and biological agents. Solutions of detoxifying reagent for chemical and biological agents are coated using small quantities of hydrophobic nanoparticles by vigorous agitation or by aerosolization of the solution in the presence of the hydrophobic nanoparticles to form a solid powder. For example, when hydrophobic fumed silica particles are shaken in the presence of IN oxone solution in approximately a 95:5-weight ratio, a dry powder results. The hydrophobic silica forms a porous coating of insoluble fine particles around the solution. Since the chemical or biological agent tends to be hydrophobic on contact with the weakly encapsulated detoxifying solution, the porous coating breaks down and the detoxifying reagent is delivered directly to the chemical or biological agent for maximum concentration at the point of need.

    Abstract: The invention relates to catalytically bleaching substrates, especially laundry fabrics, with atmospheric oxygen or air. A method of bleaching a substrate is provided that comprises applying to the substrate, in an aqueous medium, a specified organic substance which forms a complex with a transition metal, the complex catalysing bleaching of the substrate by atmospheric oxygen. Also provided is a bleaching composition comprising, in an aqueous medium, atmospheric oxygen and an organic substance which forms a complex with a transition metal, the complex catalysing bleaching of the substrate by the atmospheric oxygen, wherein the aqueous medium is substantially devoid of peroxygen bleach or a peroxy-based or -generating bleach system.

  • Patent number: 6471788
    Abstract: A method employing oxide film conversion coatings prepared using ferrate (VI) as the oxidizing agent is disclosed. Metal substrates or surfaces, such as aluminum, aluminum alloys or other metals, are contacted with an aqueous solution comprising ferrate (VI) anions to form a corrosion resistant conversion coating on the surface thereof. The ferrate anion concentration is preferably between about 0.0166% and about 1.66% by weight. The coating process is carried out by dipping, spraying, or painting at temperatures ranging from 25° C. to 100° C. for a period of time ranging from about 1 second to about 5 minutes.

  • Publication number: 20020119086
    Abstract: A process is described for regenerating an at least partly reduced catalytic redox solution, whereby said process includes at least one complexing agent of a polyvalent metal that is associated with the solution in which the solution is circulated in a regeneration zone in the presence of an oxygen-containing gas under appropriate regeneration conditions, and a regeneration effluent is recovered that is at least partly oxidized. The concentration of the oxygen that is dissolved in the regeneration effluent is measured, and the operating parameters are adjusted so as to minimize the degradation of the complexing agent and to regenerate the catalytic solution, at least in part.
