Manganese dioxide
基本信息
应用 | Manganese(IV) oxide is suitable for use in batteries. It is widely used for the selective oxidation of allylic and benzylic alcohols to aldehydes or ketones, as a co-oxidant in combination with 1,4-benzoquinone and in the allylic oxidation of olefins catalyzed by Palladium(II)?- acetate. It acts a reagent for oxidations. It is the source of manganese and all its compounds, largely used in manufacturing of manganese steel, for making amethyst glass, decolorizing glass, painting on porcelain, faience and majolica. The precipitate is used in electrotechnics, pigments, browning gun barrels, drier for paints and varnishes, printing and dyeing textiles. |
