APPLICATIONS
Nitrile is an organic compounds containing cyano group (-C≡N, containing trivalent nitrogen) which is attached to one carbon atom with the general formula RC≡N. Their names are corresponding to carboxylic acids by changing '-ic acid' to the suffix, '-onitrile' which denotes only the ≡N atom (triply bound) excluding the carbon atom attached to it, or  the suffix, '-carbonitrile' where the carbon atom in the -CN is included, whichever preserves a single letter O. Examples are acetonitrile from acetic acid and benzonitrile from benzoic acid. The prefix,  'cyano-' is used as an alternative naming system to indicate the presence of a nitrile group in a molecule for the compounds of salts and organic derivatives of hydrogen cyanide (HC≡N). Isocyanides are salts and hydrocarbyl derivatives from the isomer, HN+≡C-. Sodium cyanide, NaCN; potassium cyanide, KCN; calcium cyanide, Ca(CN)2; and hydrocyanic (or prussic) acid, HCN are examples. Chemically, the simple inorganic cyanides resemble chlorides in many ways. Organic nitriles act as solvents and are reacted further for various application including;

  · Extraction solvent for fatty acids, oils and unsaturated hydrocarbons
  · Solvent for spinning and casting and extractive distillation based on its     selective miscibility with organic compounds.
  · Removing agent of colouring matters and aromatic alcohols
  · Non-aqueous solvent for titrations and for inorganic salts
  · Recrystallization of steroids
  · Parent compound for organic synthesis
  · Solvent or chemical intermediate in biochemistry ( pesticide sequencing and     DNA synthesis)
  · High-pressure liquid chromatographic analysis
  · Catalyst and component of transition-metal complex catalysts
  · Stabilizer for chlorinated solvents
  · Chemical intermediate and solvent for perfumes and pharmaceuticals

o-Tolunitrile is used in manufacturing other organic compounds (pharmaceuticals, dyes, brightening agents, rubber chemicals)
