GENERAL DESCRIPTION

Hydrogen Peroxide is a is a strong oxidizing agent and a weak acid in water solution. The formular is similar to that of water, with an extra atom of oxygen attached, H2O2. It is completely soluble in water. Pure anhydrous hydrogen peroxide is a colorless to pale blue  syrupy liquid which decomposes violently into water and oxygen if heated above 80 C. it also decomposes in light and in the presence of metal ions or oxidizable organic materials. A small amount of stabilizer such as acetanilide is added to the solutions to retard the decomposition. One volume of hydrogen peroxide releases ten volumes of oxygen when it decomposes. It is commercially prepared by electrolysis of ammonium bisulfate or potassium bisulfate with sulfuric acid. Catalytic oxidation of hydrogen and water with oxygen using nickel, palladium, or platinum with an anthraquinone, reaction of barium peroxide with sulfuric acid and by oxidation of isopropanol with acetone are also industrial processes for the production of hydrogen peroxide. Hydrogen peroxides are marketed in concentration of 3-90% by wt as a solution in water. The most valuable property of hydrogen peroxide is that it breaks down into water and oxygen and therefore does not form any persistent, toxic residual compounds. It is used in the processes of epoxidation, oxidation, hydroxylation and reduction. Its oxidizing properties are used in the bleachings and deodorizing for textile, hair and in paper manufacture. It is also used medicinally as an antiseptic.  Its application involves the production of chemicals, e.g. organic peroxides, perhydrates. It is also used in water and sewage treatment, mining, electronics, food and cosmetic indutry.
