Brief Overview
Hydrogen peroxide 35% is a clear liquid with strong oxidizing, bleaching, and antiseptic properties. To safely handle it, precautions such as avoiding contact with flammable materials, using appropriate protective gear, working in well-ventilated areas, and thorough skin cleansing are essential. Storage and transfer should follow specific guidelines for safety.
Manufacturing 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.
