What is the applications of Manganese Dioxide Powder
Used as a depolarizer for dry batteries, a catalyst and oxidant in the synthesis industry, a coloring agent, decolorizer, and iron removal agent in the glass industry and enamel industry. Used in the manufacture of metal manganese, special alloys, ferromanganese castings, gas masks and electronic material ferrites, etc. In addition, it can also be used in the rubber industry to increase the viscosity of rubber. It can also be used as a catalyst in chemical experiments.
Organic synthesis use
Manganese dioxide is very useful in organic chemistry. The forms of manganese dioxide used for oxides vary. Because manganese dioxide has multiple crystal forms, the chemical formula can be written as MnO2·x(H2O)n, where x is between 0 and 0.5, and n can be greater than 0 . Manganese dioxide can be produced in the reaction of potassium permanganate (KMnO₄) and manganese sulfate (MnSO₄) at different pH.
One of the special chemical reactions for manganese dioxide is to convert alcohols into aldehydes. Even if the alcohol has a double bond, it will not be oxidized by manganese dioxide: cis-RCH=CHCH2OH + MnO2 → cis-RCH=CHCHO + H2O + MnO
The products in it will not be oxidized no matter how active it is. Diols can be oxidized to dialdehydes by manganese dioxide. Other manganese dioxide has many reactions and can be used to oxidize amines, aromatics and triols.
Laboratory use
Used as a catalyst for the decomposition of hydrogen peroxide to produce oxygen; as a catalyst for heating potassium chlorate to decompose to produce oxygen; thermite reaction with elemental aluminum powder to produce manganese. Used as pigments, yellow glass, etc.; react with hot concentrated hydrochloric acid to produce chlorine; react with molten caustic potassium (potassium hydroxide) in the air to produce potassium manganate; in the decomposition reaction of potassium permanganate, manganese dioxide is used as high Self-catalyst of potassium manganate.
