화학적 성질

Copper(I) bromide is a Pale green to green poeder that decomposes on exposure to light or moisture in air. It forms complexes with hydrochloric and hydrobromic acids and aqueous ammonia.

반응성 그룹	Non-Redox-Active Inorganic Compounds
Reactivity Profile	COPPER (I) BROMIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

용도

As catalyst for organic reactions.

일반 설명

White powder or crystal. Turns green to dark blue on exposure to sunlight. Sinks and mixes slowly with water.

제조 및 합성 방법

제조 방법

It is prepared pyrometallurgically with copper metal and elemental bromine in a process similar to that for copper(I) chloride. It can also be produced by the reduction of copper(II) sulfate solutions in the presence of sodium bromide using metallic copper or sulfite as the reducing agent. Copper(I) bromide is used as a polymerization catalyst in organic reactions.
