Description

General description

Acetonitrile (MeCN) is a colorless aliphatic nitrile having an ether-like odor. It readily undergoes electrophilic substitution reactions. It is formed during the industrial preparation of acrylonitrile. It is widely employed as a solvent in various studies and has high dielectric constant (37.5). Various purification procedures to obtain different grades of acetonitrile for use in different studies (polarography, spectroscopy, etc.) have been reported by many researchers.
