Bromide

(24959-67-9)
Bromide can be prepared by dissolving bromine or hydrobromic acid in water and reacting alkaline bromides. For example, sodium bromide can be obtained by reacting hydrobromic acid with sodium hydroxide, and then pure bromide can be obtained by the alcohol acid method or cation exchange method. Bromide is used to make various bromine compounds and can also be used in industries such as medicine, dyes, and fragrances. It is the basic raw material for making various inorganic bromides such as sodium bromide, potassium bromide, lithium bromide and calcium bromide and some alkyl bromides such as methyl bromide and ethyl bromide. Bromide is used in medicine to synthesize sedatives and anesthetics. Bromide is also a good solvent for some metal minerals and is used for the refining of high-purity metals.
