Acetonitrile (CAS No.75-05-8) for Textile Dyeing Industry
 

Acetonitrile , often abbreviated   MeCN   ( methyl cyanide ), is the   chemical compound   with the   formula   CH
₃ CN . 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 . ^[5]   The N≡C−C skeleton is linear with a short C≡N distance of 1.16  Å .

Acetonitrile was first prepared in 1847 by the French chemist   Jean-Baptiste Dumas .

 

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.

Catalytic   ammoxidation   of   ethylene   was also researched.

Acetonitrile is used mainly as a solvent in the purification of  butadiene  in refineries.
In the laboratory, it is used as a medium-polarity solvent that is  miscible  with water and a range of organic solvents, but not saturated hydrocarbons. 
It 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 .

Industrially, it 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 .
