Cyanogen bromide Chemical Properties,Uses,Production

Chemical Properties

white crystalline solid

Uses

Reaction with C60Ph5Cl produces a novel phenylated isoquinolino[3′,4′:1,2][60]fullerene.1

General Description

Cyanogen bromide is a colorless to white crystalline solid with a penetrating odor. Cyanogen bromide is slightly soluble in water. Cyanogen bromide is gradually decomposed by water and very rapidly by acids to give off hydrogen bromide, a flammable and poisonous gas. Contamination with many materials can cause rapid decomposition of the material. Cyanogen bromide is toxic by inhalation of its vapors or by the hydrogen cyanide from decomposition or by ingestion. Toxic oxides of nitrogen are produced in fire involving Cyanogen bromide. Cyanogen bromide is used in gold extraction, to make other chemicals, and as a fumigant.

Air & Water Reactions

Cyanogen bromide is slightly soluble in water. Cyanogen bromide is gradually decomposed by water and very rapidly by acids to give off hydrogen bromide, a poison gas.

Reactivity Profile

Cyanogen bromide is not combustible itself, but impure Cyanogen bromide decomposes rapidly and tends to explode. A violent reaction may take place on contact with large quantities of acid. Avoid physical damage, contact with acids or water, and store away from a location where water may be needed for fire control. [EPA, 1998]. Benzene and cyanogen halides yield HCl as a byproduct (Hagedorn, F. H. Gelbke, and Federal Republic of Germany. 2002. Nitriles. In Ullman Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA.).

Health Hazard

Super toxic; probable oral lethal dose in humans is less than 5 mg/kg or a taste (less than 7 drops) for a 70 kg (150 lb.) person. Vapors are highly irritant and very poisonous. Individuals with chronic diseases of the kidneys, respiratory tract, skin, or thyroid are at greater risk of developing toxic cyanide effects.

Fire Hazard

Cyanogen bromide is not combustible itself, but impure Cyanogen bromide decomposes rapidly and tends to explode. A violent reaction may take place on contact with large quantities of acid. Vapors are highly irritating. When material is heated to decomposition, Cyanogen bromide emits very toxic fumes of cyanide and bromide. Avoid water, acids. Avoid physical damage, contact with acids or water, and store away from a location where water may be needed for fire control.
