Hazard Information

General Description

Odorless black solid. Sinks and mixes with water.

Reactivity Profile

Acidic inorganic salts, such as COPPER BROMIDE(7789-45-9), 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.

Air & Water Reactions

Deliquescent. Water soluble.

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.

Flammability and Explosibility

Notclassified

reaction suitability

core: copper
reagent type: catalyst

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].

Questions And Answer

Description
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
Copper(II) bromide, CuBr2, [7789-45-9], MW 223.36, MP 498°C, d 4.77, is a black, deliquescent, monoclinic, crystalline material that obtains from warm aqueous solution. At temperatures below 29°C, the green tetrahydrate is produced. Copper(II) bromide is very soluble in water and soluble in alcohol and acetone. ;
Uses
Copper(II) bromide is used as a catalyst in organic reactions, as an intensifier in photography, and as a brominating agent.;
Preparation
Copper(II) bromide is most easily prepared by neutralization of copper(II) oxide, carbonate, or hydroxide with hydrobromic acid. It can also be produced by oxidation of copper metal with bromine water or by reaction of bromine solutions in alcohol with copper powder. ;
