Hydrogen Peroxide (50%) - Thailand (Cancelled)

Brief Overview

Hydrogen peroxide 50% 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.

Wastewater Treatment
Cleaner oxidizing agent that is used to treat wastewater, contaminated soil, and toxic air emissions.

Chemical Intermediate
Used to manufacture a wide range of organic and inorganic compounds such as hydroquinone, ketones, aldehydes, alcohols, hydro-oxyl amines, epoxy derivatives, etc.

Textile Industry
Used as a bleaching agent in the textile industry and they are more environmentally friendly than chlorine-based bleaches. Hydrogen peroxide is also used in dyes. Sulfur dyes work with an oxidation-reduction dyeing method and hydrogen peroxide is used as an oxidizing agent. Once the dyes are adsorbed onto the cellulosic, oxidation will settle the dyes permanently and changing it into a water-insoluble form.
