Abstract: The invention provides a novel method of detoxifying highly toxic chemicals, and treating surfaces contaminated, or potentially contaminated, with toxic chemical agents such as chemical warfare agents and/or industrial toxins. The methods utilizes a novel sorbent compound which comprises Mn(VII) mineral which can be either solid supported or non-solid supported. The Mn(VII) mineral can be provided in a number of different forms including creams, lotions, powders, liquids, slurries and aerosols.

Abstract: The instant method produces Mn(III) and Mn(VII) in stabilized form. Stabilized Mn(II), Mn(III), Mn(IV), and Mn(VII) are also formed on solid supports. Solid supported Mn(VII) is prepared by first reacting an H-saturated support with Mn(II) in solution. Mn(III) substituted Fe oxide coated on natural zeolite (FMNZ) is prepared by reacting Mn(II) and Fe(III) to a natural zeolite equilibrated with 2 N NaoH. The resulting Mn(IV) and Mn(III) oxide is precipitated from solution and dried to give supported Mn(IV) or Mn(III). The Mn(IV) material is reacted with 1,4-phenylenediamine (PDA) to form supported Mn(VII). In another aspect of the invention, Mn(II) is synthesized by adding 1,2-phenylenediamine dihydrochloride to uncoated and clay and-zeolite coated MnO2. Mn(II) and Mn(III) are synthesized by adding 1,2-phenylenediamine dihydrochloride and 1,4-phenylenediamine dihydrochloride, respectively, to uncoated Mn containing clays, and clay and-zeolite coated MnO2.

Abstract: An oxidation resistant fiber-reinforced composite is made by impregnating a fibrous material with a resin containing a linear polymer having a repeating unit with at least one carboranyl group, at least one silyl or siloxyl group and at least one acetylenic group. The linear polymer may then be cured to form a fiber-reinforced thermoset or may be pyrolyzed to form a fiber-reinforced ceramic. For additional protection of the fibrous material against oxidation, the fibrous material may be prewetted or coated, also with a linear polymer containing a linear polymer having a repeating unit with at least one carboranyl group, at least one silyl or siloxyl group and at least one acetylenic group, prior to being impregnated. The coating on the fibrous material may be cured to form a thermoset coating on the fibers or may be pyrolyzed to form a ceramic coating on the fibers.
