Abstract: The invention is directed to an oxidizing composition of agglutinated particles comprising an alkali metal permanganate, a binder/coating agent of an alkali metal silicate and/or alkali metal aluminate and a filler such as clay, diatomaceous earth, talc, ground silica or zeolites. The invention also is directed to an oxidizing kit which includes a pervious container and the oxidizing composition. The invention also is directed to a method of oxidizing waste materials with the kit in a substantially aqueous moving fluid stream.

Abstract: A Sorel cementitious composition which releases permanganate ion into an aqueous media over time is described. A method of making and using the composition of the invention also are described.

Abstract: A layered composition which includes a hardened core comprising at least about 50 weight percent permanganate which composition releases permanganate ion into an aqueous media over time is described. A method of making and using the composition of the invention also are described.

Abstract: Permanganate-containing pellets for gradual release or permanganate comprise an integrated body of a hydratable, self-curing cement in cured, hydrated form, and finely-divided particles of a water-soluble permanganate salt in substantially uniform distribution therein. The pellets are formed from a mixture of the permanganate salt, hydratable self-curing mineral cement, and water.

Abstract: A method is provided for selectively bleaching dyed, bleachable cotton garments. The garments are tumbled in damp condition with reuseable pre-formed solid pellets of limited porosity having abradable surfaces. The pellets comprise substantially water-insoluble cemented aggregates of mineral particles with a finely-divided particulate bleaching aent imbedded therein. The bleaching agent, which preferably is substantially uniformly distributed in the pellets, bleaches the garments by surfaces of the pellets wearing away during the garment tumbling to release the bleaching agent as the pellets contact the garments.

Abstract: Self-ignition of low rank coal is inhibited by application of a permanganate salt, such as potassium permanganate, together with a phosphorus compound, such as a phosphoric or polyphosphoric acid. The inhibitors are applied in aqueous solution following drying of the particulate coal. The combination treatment is much more effective than the use of a permanganate salt alone.

Abstract: Potassium ferrate (VI), K.sub.2 FeO.sub.4, which has been crystallized from a concentrated aqueous solution of KOH is washed with an aqueous solution of a potassium salt of an inorganic acid to remove the residual KOH. The wash solution is at an alkaline pH and contains a high concentration of the potassium salt.

Abstract: Alkali metal delta manganese dioxide hydrate, which is obtained as a by-product in the industrial oxidation of organics by KMnO.sub.4 is subjected to ion exchange reaction with heavy metal ions (copper, iron, silver, etc.). The reaction is carried out on the acid side of the pH at which a hydroxide precipitate of the heavy metal will not form, and continued until the reaction product contains less than 0.5 moles of bound alkali metal per mole of manganese. The product is recovered and prepared for catalytic use in the form of dried porous pellets. The resulting oxidation catalysts have high efficiency, long life, and optimum activity at reasonable temperatures. These catalysts can be used for applications such as the oxidation and deodorization of exhaust gases from paint drying ovens.

Abstract: Alkali metal delta manganese dioxide hydrate, which is obtained as a by-product in the industrial oxidation of organics by KMnO.sub.4 is subjected to ion exchange reaction with rare earth ions of the ceria subgroup (viz. cerium, lanthanum, etc.). By employing favorable temperature and pH conditions, a reaction product can be produced containing as little as 0.03 moles of alkalii metal per mole of manganese, and up to one mole of ceria rare earth per six moles of manganese. The separated product is prepared for catalytic use in the form of dried porous pellets. The resulting oxidation catalyst has high efficiency, long life, and optimum activity at reasonable temperatures. The catalyst can be used advantageously for applications such as the oxidation and deodorization of exhaust gases from paint drying ovens.
