Anwendungen

Hydrogen peroxide is used as an oxidizing agent to prepare propylene oxide, dibenzoyl peroxide, lauryl peroxide, peracetic acid and meta-chloroperoxybenzoic acid. It is also involved in the production of inorganic chemicals like sodium perborate and sodium percarbonate, which are used as bleaching agents in detergents. It is an associated iron catalyst and utilized for waste-water treatment to remove organic impurities through an advanced oxidation process. It is also used as a laboratory disinfectant and as a topical antiseptic. In the cosmetic industry, it is used for bleaching human hair and tooth whitening by mixing with ammonium hydroxide and baking soda respectively. Monopropellant engines using hydrogen peroxide as the fuel are commonly used for air-independent underwater propulsion applications.

Bemerkungen
