Hydrogen Peroxide (50%) - India

Brief Overview

Hydrogen peroxide 50% is a transparent liquid possessing a faintly acrid scent. It functions as a highly potent oxidizing agent, frequently employed in industrial water treatment processes to leverage its capabilities in bleaching, sanitizing, and oxidation. This variant of hydrogen peroxide is recognized for its robust oxidizing, bleaching, and antiseptic attributes.

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.

Application

- Industrial water treatment: Hydrogen peroxide 50% is used as a processing material in industrial water treatment, capitalizing on its bleaching, sanitizing, and/or oxidizing properties
- Bleaching agent: Hydrogen peroxide 50% is used as a bleaching agent in the textile and paper industries
- Chemical production: Hydrogen peroxide 50% is used in the production of various organic compounds in the chemical industries
- Oxidation and hydroxylation reactions: Hydrogen peroxide 50% is used in oxidation and hydroxylation reactions
- Disinfectant: Hydrogen peroxide 50% is used as a sterilizer and disinfectant in wastewater treatment, dentistry, and other applications
