GENERAL DESCRIPTION & APPLICATIONS

Nitrile is any of a family of organic compounds containing cyano group (-C¡ÕN) which is attached to a carbon atom and having the general formula RC¡ÕN. Their names are corresponding to carboxylic acids by changing '-ic acid' to '-onitrile', or '-nitrile', whichever preserves a single letter o. Examples are acetonitrile from acetic acid and benzonitrile from benzoic acid. Pendant nitriles are often named as ¡°cyano¡± substituents. Cyanoacetic acid, the half nitriled-malonic acid, and its esters are basic chemical intermediates for the production of;
  • Malonates
  • Barbitals
  • Caffeine, Betaine, Vitamin B
  • Pharamceuticals
  • Glycine
  • Surfactancts
  • Agrochemicals
  • Dyestuffs
  • Adhesives
  • Indigo dyes
  • Herbicides
  • Engineering plastics

Although nitriles don't have a carbonyl group, they are often considered as derivatives of carboxylic acids. Nitrile undergoes acid hydrolysis to form a carboxylic acid. Nitrile is reduced to form amine in the presence of nickel catalyst. Grignard reagents add to nitriles, forming a relatively stable imino derivative which can be hydrolyzed to a ketone. Metaloimine is hydrolyzed to give beta-ketoester. Nitrile undergoes a sequence of nucleophilic additions with an alcohol under acid catalysis, called nitrile alcoholysis. Nitriles are hydrolyzed to carboxylic acids, alcoholyzed to esters, reduced to amines, cyclyzed to pyridine derivatives.
