akryylinitriilimonomeerin

Akryylinitriilimonomeeri, commonly known as acrylonitrile monomer or vinyl cyanide, is an organic compound with the chemical formula CH2=CHCN. It is a colorless, volatile liquid with a pungent odor. Acrylonitrile is a crucial intermediate in the production of various polymers and copolymers, making it a significant commodity chemical.

The primary industrial method for producing acrylonitrile is the SOHIO process, which involves the ammoxidation of propylene. This reaction uses propylene, ammonia, and oxygen in the presence of a catalyst, typically based on bismuth molybdate, to yield acrylonitrile, water, and acetonitrile. Other methods, though less common, include the oxidation of propylene with nitric acid and the dehydration of cyanoethanol.

Acrylonitrile monomer is extensively used in the manufacture of acrylic fibers, which find applications in textiles, carpets, and upholstery. It is also a key component in the production of acrylonitrile butadiene styrene (ABS) resins, a robust thermoplastic used in automotive parts, electronic housings, and consumer goods. Furthermore, it is used to make nitrile rubber, known for its resistance to oil and chemicals, and styrene-acrylonitrile (SAN) copolymers.

Due to its reactivity and potential health hazards, acrylonitrile monomer is handled with care in industrial settings. It is flammable and can be toxic if inhaled or absorbed through the skin. Strict safety protocols are in place for its storage, transportation, and processing to minimize risks to workers and the environment.
