On an industrial scale, H2O2 is prepared by oxidation of 2-ethylanthraquinol.
Hydrogen peroxide is the simplest kind of peroxide available. It is a colourless liquid and is used in aqueous solution for safety reasons. It acts as a bleaching agent and is also used as a disinfectant.
Auto-Oxidation Method of Preparation of H2O2
2-ethylanthraquinol undergo auto-oxidation to produce hydrogen peroxide and 2-ethyl anthraquinone.
