Bromobenzyl cyanide Chemical Properties,Usage,Production

Chemical Properties

Light yellow, gas, slightly water soluble, soluble in organic solvents.

Uses

Tear gas in riot control and a war gas, and agri- cultural fungicide to control certain fungal diseases of stone fruit.

Production Methods

The preparation of bromophenylacetonitrile consists of three steps: chlorination of toluene to form benzyl chloride, (2) conversion of benzyl chloride to benzyl cyanide by action of sodium cyanide in alcoholic solution, and bromination of benzyl cyanide with bromide vapor in the presence of sunlight.

Hazard

Toxic, lacrimator.

Safety Profile

Poison by ingestion. Moderately toxic to humans by inhalation. When heated to decomposition it emits very toxic fumes of NOx, Br-, and CN-. See also NITRILES.
