过氧化氢（35%） - 泰国

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.

Hydrogen peroxide is primarily used as a bleach and disinfectant. It helps in removing stains and providing
a brighter appearance to laundry and cleaning products.
