Can be prepared by the dehydration of benzamide at high temperatures in the presence of catalyst. Another accessible route is reaction between cuprous cyanide or NaCN with bromobenzene in DMSO, known as Rosenmund–von Braun reaction.
- C6H5CH3 + 3/2 O2 + NH3 → C6H5(CN) + 3 H2O
- Make aromatic compounds
- Make benzamide
Benzonitrile is irritant.
In closed bottles, away from light and air.
Can be neutralized by mixing it with a flammable solvent then incinerated outside or in a fume hood.
