Hydrogen peroxide is used as an oxidant in organic synthesis and participates in a variety of chemical reactions, such as the oxidation of alcohols, the oxidation of aldehydes, etc.

It can also be used in the preparation of other chemicals such as peracetic acid, propylene oxide,

Electronic grade hydrogen peroxide is mainly used in the manufacturing and processing of semiconductor and electronics industries. In the semiconductor industry, electronic grade hydrogen peroxide is often used to clean and remove surface contaminants, such as organic matter, metal ions and silicides on the surface. In addition, electronic grade hydrogen peroxide can also be used in processes such as etching, oxidation and coating.

In the textile industry, hydrogen peroxide is a commonly used bleaching agent. It can bleach natural fibers such as cotton, linen, silk, and chemical fibers. For pure cotton fabrics, by using hydrogen peroxide for bleaching under high temperature and alkaline conditions, the natural pigments in the fabric can be destroyed and the fabric can be whitened.

During the dyeing process, for some reducing dyes, hydrogen peroxide needs to be used for oxidation treatment so that the dye forms a stable insoluble color lake on the fiber, thereby improving the dyeing fastness.

Food-grade hydrogen peroxide is a highly effective disinfectant that can kill various kinds of bacterial propagules, fungi, mycobacterium tuberculosis, bacterial spores and various viruses. It is an efficient, non-toxic, odorless and environmentally friendly product, as the residue after sterilization can be decomposed into water and oxygen.

Food-grade hydrogen peroxide is a green, safe and efficient disinfectant. It is the preferred product for industries such as dairy production, beverages, beer, juice, food processing, pharmaceuticals, drinking water, hospitals, and public places.

Similar to the bleaching principle in the textile industry, hydrogen peroxide can be used for bleaching pulp. It can remove impurities such as lignin and pigments in pulp and improve the whiteness of paper. In the modern papermaking industry, due to the improvement of environmental protection requirements, hydrogen peroxide has been widely used as a relatively environmentally friendly bleaching agent. Compared with traditional chlorine-containing bleaching agents, the wastewater after hydrogen peroxide bleaching is easier to handle and less polluting to the environment.

In the process of waste paper recycling, hydrogen peroxide can be used for deinking. It can oxidize and decompose the pigments and binders in the ink, so that the ink can be separated from the paper, and the waste paper can be made into paper again.

Hydrogen peroxide can oxidize many organic pollutants in wastewater, such as phenols, cyanide, sulfide, etc. For wastewater containing heavy metal ions, hydrogen peroxide can also convert heavy metal ions into a form that is easier to precipitate through redox reactions. For example, when treating cyanide-containing wastewater, hydrogen peroxide can oxidize cyanide into cyanate, which is further decomposed into carbon dioxide and nitrogen, thereby reducing the toxicity of the wastewater.

When treating some industrial waste gases such as sulfur dioxide, hydrogen peroxide can react with it and convert it into sulfuric acid, thereby purifying the waste gas. This method can effectively reduce the emission of harmful gases and protect the environment.
