Cupric bromide Chemical Properties,Uses,Production


Cupric bromide is a kind of inorganic compound obtained through the reaction between copper oxide and hydrobromic acid. It can be used in laser, generating pulse yellow and green light. The cupric bromide laser is an important technology used in dermatology for the treatment of pigmented lesion and vascular lesions. It can also be used in living radical polymerization and as an intensifier in photographic processing. It is also a brominating agent used in organic synthesis. In addition, it is a kind of highly efficient catalyst in the direct alkynylation of azoles.

Chemical Properties

Black crystal


As intensifier in photography; as brominating agent in organic synthesis; as humidity indicator; as wood preservative; in solid-electrolyte battery; as stabilizer for acetylated polyformaldehyde.

General Description

Odorless black solid. Sinks and mixes with water.

Air & Water Reactions

Deliquescent. Water soluble.

Reactivity Profile

Acidic inorganic salts, such as Cupric bromide, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Health Hazard

Inhalation of dust causes irritation of throat and lungs. Ingestion of large amounts causes violent vomiting and purging, intense pain, collapse, coma, convulsions, and paralysis. Contact with solutions causes eye irritation; contact with solid causes severe eye surface injury and skin irritation.

Fire Hazard

Special Hazards of Combustion Products: Irritating hydrogen bromide gas may form in fire.

Purification Methods

Crystallise it twice by dissolving it in water (140mL/g), filtering to remove any Cu2Br2, and concentrating under vacuum at 30o until crystals appear. The cupric bromide is then allowed to crystallise by leaving the solution in a vacuum desiccator containing P2O5 [Hope et al. J Chem Soc 5226 1960, Glemser & Sauer in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1009 1965].
