CAS # 75-05-8


Acetonitrile is the chemical compound with the formula C2H3N. This colourless liquid is the simplest organic nitrile (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic). It is produced mainly as a byproduct of acrylonitrile manufacture. It is used as a polar aprotic solvent in organic synthesis and in the purification of butadiene

·        Acetonitrile is primarily used as an extraction solvent for butadiene.

·        It is used as a chemical intermediate in pesticide manufacturing; and as a solvent for both inorganic and organic compounds.

·        It is also included as a starting material for the production of acetophenone, alpha- naphthalenacetic acid, thiamine, and acetamidine; to remove tars, phenols, and coloring matter from petroleum hydrocarbons not soluble in Acetonitrile.

·        In the laboratory, acetone is used as a polar aprotic solvent in a variety of organic reactions, such as SN2 reactions. The use of acetone solvent is also critical for the Jones oxidation. It is a common solvent for rinsing laboratory glassware because of its low cost and volatility; however, it does not form a zoetrope with water.

·        It is used in the production of acrylic fibers; and in pharmaceuticals, perfumes, nitrile rubber, and ABS (Acrylonitrile-butadiene-styrene) resins.
