Uses and applications
What the substance is used for, by industry and function
Pharmaceutical intermediate. (Hydrogen bromide gas).
Isomerization of conjugated diolefins. (Hydrobromic acid).
Analytical chemistry, solvent for ore minerals. (Hydrobromic acid).
Hydrogen bromide is utilized in: production of inorganic bromides by reaction with the appropriate aqueous solution or slurry of metal hydroxides, oxides, or carbonates, production of organic bromides by reaction with alkyl alcohols or alkenes, reaction with alkynes to form bromoalkenes, opening epoxides and lactones, as a catalyst for oxidations, and alkylations and condensations in organic chemistry. (Hydrogen bromide gas).
Hydrobromic acid is used industrially in the production of inorganic bromides, alkyl bromides from alcohols, in cleaving acyclic and cyclic ethers, in adding to the cyclopropane group by ring opening, and as an alkylation catalyst.
Industrial uses: Chemical reaction regulator, Plating agent, Solvent, Intermediate, Processing aids, specific to petroleum production, Etching agent, Catalyst, Ion exchange agent.

How it is made
Hydrogen bromide is prepared commercially by the direct gas-phase reaction of hydrogen and bromine ... The reaction can be conducted without catalyst by maintaining a self-sustaining flame within an enclosed burner. (Hydrogen bromide gas)
(1) By passing hydrogen with bromine vapor over warm platinum sponge which acts as a catalyst, (2) As a by-product in the bromination of organic compounds. (Hydrogen bromide gas)
By dissolving hydrogen bromide in water or by distilling from a mixture of sodium bromide and 50% sulfuric acid. (Hydrobromic acid)
