Description and Uses

Benzonitrile is a colorless, oily liquid. It hasan almond odor. Molecular weight = 103.13. Boilingpoint = 191℃; Freezing/Melting point = - 13℃; Criticaltemperature= 426℃; Critical pressure = 611 psia; Specificgravity (H2O:1) = 1.01 at 25℃; Relative vapor density(air=1) =3.6; Electrical conductivity =2 3 106 pS/m;Ratio of specific heats of vapor (gas) = 1.091; Latentheat of vaporization = 3.67 3 105 J/kg; Heat ofcombustion =-351 3 105 J/kg. Explosive limits in air:Lower= 1.4%, Upper = 7.2%; Flash point = 71℃;Autoignition temperature = 550℃. Hazard Identification(based on NFPA-704 M Rating System): Health 2,Flammability 1, Reactivity 0. Poor solubility in water.

The most important commercial use for benzonitrile is the synthesis of benzoguanamine, which is a derivative of melamine and is used in protective coatings and molding resins. It is used intermediate for rubber chemicals; solvent for nitrile rubber, specialty lacquers, and many resins and polymers, and for many anhydrous metallic salts.
