Acetonitrile

CAS RN: 75-05-8

Major Uses

Solvent in hydrocarbon extraction processes, especially for butadiene; specialty solvent; intermediate; catalyst; separation of fatty acids from vegetable oils; manufacturing of synthetic pharmaceuticals.
In organic synthesis as starting material for acetophenone, alpha-naphthaleneacetic acid, thiamine, acetamidine. To remove tars, phenols, and coloring matter from petroleum hydrocarbons which are not soluble in acetonitrile. To extract fatty acids from fish liver oils and other animals and vegetable oils. Polar solvent in non-aqueous titrations; non-aqueous solvent for inorganic salts. In, ... UV, and electrochemistry applications. Facilitates reactions between organic substrates and inorganic materials.
Acrylic fibers; pharmaceuticals; perfumes; nitrile rubber; ABS /Acrylonitrile butadiene styrene/ resins.
Starting material for many types of nitrogen-containing compounds, eg, amides, amines, higher molecular weight mono- and dinitriles; halogenated nitriles; ketones; isocyanates; and heterocycles, eg, pyridines and imidazolines.
Widely used as a recoverable reaction medium, particularly for the preparation of pharmaceuticals; used in the separation of other olefins (eg propylene, isoprene, allene, and methylactylene) from hydrocarbon streams; used as a solvent for polymers, spinning fibers, and casting and molding plastics; used with spectrophotometry, electrochemistry, and high pressure liquid chromatography; used as a catalyst and ingredient in transition metal complex catalysts, in the photographic industry, and for the extraction and refining of copper and by-product ammonium sulfate; used for dyeing textiles and in coating compositions; used as a stabilizer for chlorinated solvents in the presence of aluminum; used in the manufacture of perfumes and as reagent in a wide variety of compounds.
Used as solvent in lithium-sulfur dioxide electrochemical cells.
Approximately 50% of acetonitrile produced is used by the pharmaceutical industry to manufacture different products like insulin, antibiotics and vitamins.
