[Chemical Knowledge]：The nature of hydrogen peroxide, use, upstream and downstream raw materials, storage methods, the nature and use of hydrogen peroxide is what?

Hydrogen peroxide properties

Hydrogen peroxide, the chemical name of hydrogen peroxide (H? O?), is a colorless transparent liquid with strong oxidizing and weak acidity. It has a relative density of 1.45, a boiling point of about 150°C, and a melting point of -0.43°C. Hydrogen peroxide is easily soluble in water and releases a large amount of oxygen when dissolved, forming an aqueous solution with extremely high oxygen content. Its chemical properties are more active, with many organic and inorganic redox reactions, which makes it widely used in industry and medicine and other fields.

Hydrogen peroxide uses

Industrial use

In the industrial field, hydrogen peroxide is mainly used for bleaching, oxidation, disinfection and environmental protection. In the paper and textile industries, hydrogen peroxide is used to bleach pulp and textiles because it does not produce harmful by-products and has better environmental performance than traditional bleaching agents. In the chemical industry, hydrogen peroxide as an oxidant for the production of ethylene oxide, benzoyl peroxide and other chemicals. Hydrogen peroxide is also used for sewage treatment and air purification, because of its decomposition to generate water and oxygen, no pollution to the environment.

Medical use

The application of hydrogen peroxide in the field of medicine mainly focuses on disinfection and sterilization. Because of its strong oxidation, hydrogen peroxide can effectively kill bacteria, viruses and fungi, and is often used as an external disinfectant. Hydrogen peroxide is also used for oral hygiene, such as teeth whitening and disinfection of oral ulcers. At a certain concentration, hydrogen peroxide is also used to treat some skin diseases, with the effect of cleaning and promoting wound healing.

Other uses

Hydrogen peroxide is also widely used in food processing, electronics industry and agriculture. In the food industry, hydrogen peroxide is used to disinfect packaging materials and food processing equipment. In the electronics industry, hydrogen peroxide is used to clean semiconductor materials and circuit boards. In agriculture, hydrogen peroxide can be used for seed treatment and plant disease control, because it has good bactericidal effect and no residue.

Upstream and downstream raw materials

Upstream raw materials

The production of hydrogen peroxide mainly depends on industrial-grade raw materials, the most important of which are hydrogen and oxygen. Modern production methods of hydrogen peroxide mostly use anthraquinone method, through hydrogen and oxygen in the role of catalyst to generate anthraquinone derivatives, and then through the regeneration reaction to obtain hydrogen peroxide. The manufacturing process also requires the use of chemicals such as solvents (such as benzene) and catalysts (such as palladium).

Downstream Products

As an important chemical raw material, hydrogen peroxide has a wide variety of downstream products. Common are bleaches, disinfectants, oxidants and various organic compounds. Hydrogen peroxide is widely used in the production of ethylene glycol, benzoyl peroxide and other chemical products, and plays an important role in pharmaceutical, textile, papermaking, environmental protection and other fields. Its market demand is closely related to the development of these industries.

storage method

Storage requirements

Hydrogen peroxide has strong oxidation and instability, so its storage has strict requirements. Containers for storing hydrogen peroxide must be made of corrosion-resistant materials, such as high-density polyethylene or stainless steel, to avoid contact with iron, copper and other metals to prevent decomposition reactions. Hydrogen peroxide should be stored in a cool, well-ventilated place, avoid direct sunlight and high temperature environment, to prevent its decomposition to produce a large amount of oxygen, causing safety hazards.

Safety measures

When storing and transporting hydrogen peroxide, a series of safety measures should be taken. The storage area shall be well ventilated and equipped with personal protective equipment such as emergency eyewash and protective clothing. During transportation, ensure that the container is well sealed to prevent leakage and vibration, and post obvious dangerous goods signs. Hydrogen peroxide is a hazardous chemical, and operators need to be professionally trained to be familiar with its physical and chemical properties and emergency treatment measures.

emergency treatment

In case of hydrogen peroxide leakage, the site personnel shall be evacuated quickly and the leakage liquid shall be diluted with a large amount of water to prevent it from contacting with inflammables or reducing agents. Because hydrogen peroxide is highly corrosive, protective equipment should be worn during treatment to avoid skin and eye contact. If accidentally contact, should immediately rinse with plenty of water, and timely medical treatment. Oxygen produced by the decomposition of hydrogen peroxide is easy to support combustion, so special attention should be paid to fire prevention.

Conclusion

Hydrogen peroxide has been widely used in industry, medicine and daily life because of its excellent oxidation performance and environmental protection characteristics. Its production relies on upstream raw materials such as hydrogen and oxygen, while its downstream products involve multiple industries and the market demand is stable. Due to its active chemical nature, strict safety measures should be taken during storage and transportation. In the future, with the technological progress and the increase of environmental protection demand, the application prospect of hydrogen peroxide will be broader.
