Specification :

Benzonitrile, derived mainly from benzoic acid reaction with lead thiocyanate by heating, is a clear liquid; boils at 191 C. It reacts violently with strong acids to produce toxic hydrogen cyanide. It decomposes on heating producing very toxic fumes, hydrogen cyanide, nitrous oxides. Benzonitrile is used as a solvent and chemical intermediate for the synthesis of pharmaceuticals, dyestuffs and rubber chemicals through the reactions of alkylation, condensation, esterification, hydrolysis, halogenation or nitration. Benzonitrile and its derivatives are used in the manufacture of lacquers, polymers and anhydrous metallic salts as well as intermediates for pharmaceuticals, agrochemicals, and other organic chemicals.
