Applications
Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. Specifically, acetonitrile is fed into the top of a distillation column filled with hydrocarbons including butadiene, and as the acetonitrile falls down through the column, it absorbs the butadiene which is then sent from the bottom of the tower to a second separating tower. Heat is then employed in the separating tower to separate the butadiene.


In the laboratory, Acetonitrile is used as a medium-polarity solvent that is miscible with water and a range of organic solvents, but not saturated hydrocarbons. 
Acetonitrile has a convenient liquid range and a high dielectric constant of 38.8. With a dipole moment of 3.92 D, acetonitrile dissolves a wide range of ionic and nonpolar compounds and is useful as a mobile phase in HPLC and LC–MS.


Acetonitrile is widely used in battery applications because of its relatively high dielectric constant and ability to dissolve electrolytes. For similar reasons it is a popular solvent in cyclic voltammetry.


Acetonitrile is ultraviolet transparency UV cutoff, low viscosity and low chemical reactivity make it a popular choice for high-performance liquid chromatography (HPLC).


Acetonitrile plays a significant role as the dominant solvent used in the manufacture of DNA oligonucleotides from monomers.


Industrially, Acetonitrile is used as a solvent for the manufacture of pharmaceuticals and photographic film.


Organic synthesis
Acetonitrile is a common two-carbon building block in organic synthesis of many useful chemicals, including acetamidine hydrochloride, thiamine, and α-napthaleneacetic acid.Its reaction with cyanogen chloride affords malononitrile.


As an electron pair donor
Acetonitrile has a free electron pair at the nitrogen atom, which can form many transition metal nitrile complexes.
 Being weakly basic, Acetonitrile is an easily displaceable ligand. For example, bis(acetonitrile)palladium dichloride is prepared by heating a suspension of palladium chloride in acetonitrile:


PdCl2 + 2 CH3CN → PdCl2(CH3CN)2
A related complex is [Cu(CH3CN)4]+. The CH3CN groups in these complexes are rapidly displaced by many other ligands.
Acetonitrile also forms Lewis adducts with group 13 Lewis acids like boron trifluoride. In superacids, it is possible to protonate acetonitrile.


Production
Acetonitrile is a byproduct from the manufacture of acrylonitrile. Most is combusted to support the intended process but an estimated several thousand tons are retained for the above-mentioned applications.Production trends for acetonitrile thus generally follow those of acrylonitrile. 
Acetonitrile can also be produced by many other methods, but these are of no commercial importance as of 2002. Illustrative routes are by dehydration of acetamide or by hydrogenation of mixtures of carbon monoxide and ammonia.In 1992, 14,700 tonnes (32,400,000 lb) of acetonitrile were produced in the US.
