What is the use of acrylonitrile? Explain the application field

Acrylonitrile (Acrylonitrile, referred to as AN) is an important chemical raw material, widely used in many industries. As an organic compound, acrylonitrile has unique chemical properties that make it the basis of many high value-added products. This article will analyze the main uses of acrylonitrile in detail to help readers better understand its importance in modern industry.

1. Acrylonitrile in synthetic fiber application

One of the best known uses of acrylonitrile is in the field of synthetic fibers, especially polyacrylonitrile (PAN). Polyacrylonitrile is an important high-performance fiber raw material, which is widely used in the manufacture of chemical fibers, such as acrylic fibers. Acrylic fiber has excellent heat resistance, chemical resistance and UV resistance, so it is widely used in clothing, carpets, car seats and other fields.

Polyacrylonitrile fibers are also precursors for the production of carbon fibers. Carbon fiber has extremely high strength and light weight characteristics, and is widely used in high-end fields such as aerospace, automobiles, and sports equipment. Therefore, the use of acrylonitrile in the field of synthetic fibers has had a profound impact on many industries.

2. Acrylonitrile in rubber industry application

Another important use of acrylonitrile is in the rubber industry. Acrylonitrile-butadiene rubber (NBR) formed by the copolymerization of acrylonitrile and butadiene is a widely used synthetic rubber material. NBR rubber has excellent oil resistance, high temperature resistance and aging resistance, and is widely used in the manufacture of automotive seals, oil pipes, gaskets and other high-demand rubber products.

The addition of acrylonitrile has greatly improved the resistance of NBR rubber to chemicals, oils and solvents. Therefore, the application of acrylonitrile in the rubber industry is very important to improve the performance of rubber materials.

3. Acrylonitrile in plastics industry

In addition to applications in the synthetic fiber and rubber industries, acrylonitrile also plays an important role in the plastics industry. Acrylonitrile is a key raw material for the production of ABS plastics (acrylonitrile-butadiene-styrene copolymer). ABS plastic with its good impact resistance, heat resistance and formability, widely used in automotive, home appliances, electronic products shell and other fields.

ABS plastic has excellent comprehensive properties, so it has become the preferred material for many manufacturing industries. The role of acrylonitrile in the plastics industry cannot be ignored, and it is an important basis for the production of high-performance plastics.

4. Acrylonitrile in chemical synthesis

Acrylonitrile is not only a raw material for many polymer materials, but also an important chemical intermediate, which plays an important role in the synthesis of chemicals. Acrylonitrile can be converted to cyanide, acrylic acid and its ester compounds, etc. These derivative products are widely used in many fields, such as medicine, agriculture, coatings, dyes and so on.

For example, acrylonitrile reacts with hydrated ammonia to form hydrogen cyanide (HCN), which is a key raw material in many organic synthesis reactions. Acrylic acid and its esters also have important applications in the production of coatings, adhesives and plastics.

5. Acrylonitrile in water treatment potential

In recent years, acrylonitrile has also shown certain application potential in the field of water treatment. Acrylonitrile-based polymers can be used in water treatment processes, especially in sewage treatment and water purification, playing an important role. Through the chemical modification of polyacrylonitrile materials, more efficient water treatment materials can be obtained to improve the water treatment effect.

For example, acrylonitrile-derived polymers can be used to remove heavy metal ions, organic pollutants and other harmful substances in water, providing new technical support for water resources protection and environmental governance.

Conclusion: Acrylonitrile is widely used

The use of acrylonitrile covers many important industries, from synthetic fibers, rubber to plastics, to the synthesis of chemicals and water treatment, which are indispensable raw materials in modern industry. It not only plays an important role in traditional fields, but also shows great application potential in emerging technology fields. Therefore, understanding the use of acrylonitrile will help us to better understand its important position in industrial development and future development trends.
