Application and production process of copper bromide
Copper bromide is an inorganic compound with the formula CuBr2. The substance is a light gray or black crystalline or crystalline powder that is highly soluble in water and gradually becomes light green when exposed to air. Relative density 4.98, melting point 497°C, boiling point 1345°C. Soluble in water, acid and organic solvents such as ethanol and acetone.
Character
The appearance of copper bromide is light gray or black crystal or crystalline powder, with delixing. It is highly soluble in water; Soluble in ethanol, acetone, pyridine, ammonia; Insoluble in benzene. Bromine is released on ignition to form cuprous bromide. Its solution is acidic and is prepared by the reaction of hydrobromic acid with copper oxide.
Use
Copper bromide (CuBr) can be used as a photosensitizer. Used as a brominating agent in organic synthesis; It can also be used in copper vapor lasers, when hydrogen bromide placed in the catheter and molten copper in the condition of discharge reaction to form copper bromide vapor, this laser can produce yellow or green light, can be used in dermatology. Copper bromide can also be used as a bromination reagent, oxidation reagent, and Lewis acid reagent.
