Acrylonitrile is an organic compound with the formula CH 2 CHCN and the structure H 2 C=CH−C≡N. It is a colorless, volatile liquid although commercial samples can be yellow due to impurities . It has a pungent odor of garlic or onions. [ 4 ]
Acrylonitrile is commonly employed as a comonomer with styrene, e.g. acrylonitrile, styrene and acrylate plastics. Labelling of items of clothing with acrylic (see acrylic fiber) means the polymer consists of at least 85% acrylonitrile as the monomer. A typical comonomer is vinyl acetate, which can be solution-spun readily to obtain fibers that ...
Acrylamide can be prepared by the hydration of acrylonitrile, which is catalyzed enzymatically: [6] CH 2 =CHCN + H 2 O → CH 2 =CHC(O)NH 2. This reaction also is catalyzed by sulfuric acid as well as various metal salts. Treatment of acrylonitrile with sulfuric acid gives acrylamide sulfate, CH=CHC(O)NH 2 ·H 2 SO 4.
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

The main industrial route to this nitrile is the hydrogenation of acrylonitrile. It is also prepared by the ammoxidation of propanol (propionaldehyde can also be used instead): [7] CH 3 CH 2 CH 2 OH + O 2 + NH 3 → CH 3 CH 2 C≡N + 3 H 2 O. Propionitrile is a byproduct of the electrodimerisation of acrylonitrile to adiponitrile.
Methyl acrylate is an organic compound, more accurately the methyl ester of acrylic acid.It is a colourless liquid with a characteristic acrid odor. It is mainly produced to make acrylate fiber, which is used to weave synthetic carpets. [6]
Styrene acrylonitrile resin (SAN) is a copolymer plastic consisting of styrene and acrylonitrile. It is widely used in place of polystyrene owing to its greater thermal resistance. The chains of between 70 and 80% by weight styrene and 20 to 30% acrylonitrile. [ 1 ]
