It serves as a potent oxidizer, commonly applied in industrial water treatment for its capabilities in bleaching, sanitizing, and oxidizing. This solution is recognized for its robust oxidizing, bleaching, and antiseptic attributes.
Manufacturig Process
There are two main methods to produce H2O2 as described below:
Method 1: Auto-oxidation of ethyl anthraquinones in a solvent such as toluene or ethylbenzene. The product ethyl anthraquinone is reduced by hydrogen over supported nickel or platinum catalyst to regenerate back the starting material, ethyl anthraquinone for continuous production of H2O2.
Method 2: Electrolytic conversion of aqueous sulfuric acid to peroxydisulfate followed by hydrolysis to H2O2. This is also known as the Weissenstein process.
