Acrylonitrile is an important organic chemical raw material and has a wide range of uses. This article will detail the properties of acrylonitrile, production methods, safety and use of knowledge.
1. the properties of acrylonitrile
acrylonitrile is a colorless transparent liquid with a special pungent odor. Its molecular formula is C3H3N, structural formula is CH2 = CH-CN. Acrylonitrile has a boiling point of 107.1°C, a melting point of -83°C and a density of 0.806g/cm3. It is poorly soluble in water and easily soluble in organic solvents. Acrylonitrile has strong chemical activity and is prone to addition, polymerization, oxidation and other reactions.
2. of acrylonitrile production methods
of acrylonitrile production methods are mainly cyanide, acetylene and propylene ammoxidation method. Among them, propylene ammoxidation is the most important production method in the world, which uses propylene, ammonia and air as raw materials, under the action of catalyst, through oxidation, absorption, refining and other processes to produce acrylonitrile.

of
3. Acrylonitrile
Acrylonitrile is a toxic compound with high toxicity to humans and animals. Long-term exposure to acrylonitrile can cause damage to the nervous system, digestive system and respiratory system. Therefore, in the process of production and use, it is necessary to strictly abide by the safety operation procedures, strengthen ventilation and protective measures to protect the health of workers and the public.
4. the use of acrylonitrile
acrylonitrile has a wide range of uses, mainly used in the production of acrylic fiber, nitrile rubber, ABS resin and other chemical products.
1. Acrylic fiber: Acrylonitrile is the main raw material for the production of acrylic fiber. Acrylic fiber has the advantages of softness, fluffy, and good thermal performance. It is widely used in textiles, clothing and other fields.
2. Nitrile rubber: Acrylonitrile-butadiene rubber can be prepared by copolymerization of acrylonitrile-butadiene rubber. Nitrile rubber has excellent oil resistance, wear resistance, anti-aging and other properties, and is widely used in automobiles, aerospace, petrochemical and other fields.
3. ABS resin: ABS resin can be prepared by copolymerization of acrylonitrile, styrene and butadiene. ABS resin has excellent impact strength, heat resistance, weather resistance and other properties, and is widely used in home appliances, automobiles, construction and other fields.
In conclusion, acrylonitrile, as an important organic chemical raw material, has a wide range of applications in the field of chemical production raw materials.
