APPLICATIONS
|
Cyanohydrins are organic compounds which contain both cyano and hydroxyl groups
linked to the same carbon atom usually. Cyanohydrins are obtained from the reactions of
aldehydes (or ketones) with hydrogen cyanide in base. They are versatile
intermediates for the synthesis of organic compounds including amino nitriles;
alpha-hydroxy acids, esters and amides; alpha-, beta- unsaturated acids, esters,
nitriles as well as beta-aminoalcohols. Ethylene Cyanohydrin is used to manufacture insecticides, pharmaceuticals
and flavouring agents.
It is used to prepare certain organic chemicals such as methacrylates. |

GENERAL DESCRIPTION OF NITRILE |
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. |
