Use

Acetonitrile is used as a solvent both in industry and in the laboratory, as a rodenticide, and in the denaturation of alcohol. Because of both its solvent properties and volatility, it is useful for extracting vegetable and animal oils and dissolving hydrocarbons, oils, and greases. Acetonitrile is used for the purification of acetylene and artificial textile fibers, and as an antioxidant for rubber (Dequidt et al 1974). It has also been used to extract herbicide residues from soils (Smith 1980), to remove tars and other compounds from petroleum hydrocarbons, and to extract fatty acids from vegetable and fish liver oil. Acetonitrile is now a standard solvent component in reversed-phase high-performance liquid chromatography. It is the starting point for the syntheses of a number of organic compounds such as carboxylic acids and various nitrogen derivatives (Smiley 1981).
