In chemical synthesis, it is an important oxidant and participates in a variety of organic synthesis reactions, such as the preparation of chemical raw materials such as ethylene oxide and caprolactam. It can also be used to treat industrial wastewater containing organic pollutants, oxidizing and decomposing organic pollutants into harmless substances to achieve the purpose of purifying water quality.

Packaging
Appropriate materials should be selected to store hydrogen peroxide. Generally speaking, plastic containers (such as polyethylene, polypropylene) or glass containers are more commonly used. They have good chemical stability, are not easy to react with hydrogen peroxide, and can ensure the quality of hydrogen peroxide.
Storage environment
1. Storage away from light: Hydrogen peroxide is light-sensitive, and light will accelerate its decomposition. It should be stored in a light-proof container and placed in a dark place.
2. Low-temperature storage: Avoid high temperature environment, as high temperature will accelerate its decomposition.
3. Good ventilation: The storage place should be well ventilated to avoid danger caused by gas accumulation.

FAQ
Q: Can hydrogen peroxide deodorize?
A:The main component of hydrogen peroxide is hydrogen peroxide, which is not stable. It is easy to produce oxygen when left in the air for a long time, which can play the role of deodorization, antibacterial and decolorization.
Q: Can hydrogen peroxide disinfect?
A: The killing effect of hydrogen peroxide on bacteria and viruses mainly comes from its strong oxidizing property. When hydrogen peroxide comes into contact with microorganisms, it can quickly decompose new ecological oxygen. The new ecological oxygen enters the microorganisms, denatures the related enzymes of bacteria, or destroys the nucleic acid structure of viruses, thereby killing bacteria and inactivating viruses.
Q: Can hydrogen peroxide be used to wash clothes?
A:Hydrogen peroxide has two uses in washing clothes. The first is to deal with the color matching of clothes, and the second is to enhance the effect of stain removal. First, let's talk about the first use-bleaching and removing the color matching of clothes: for example, the shirt above is accidentally self-dyed when washed, or it is dyed by other clothes. For such clothes, we can choose hydrogen peroxide bleaching treatment.
