C 10 H 12 + 4 Br 2 → C 10 H Referring to Fig. It may be prepared in the laboratory by distillation of a solution of sodium bromide or potassium bromide with phosphoric acid or sulfuric acid:[15]. Chemical industries also use it for hydrochloric acid production. It should be stored only when the temperature does not exceed 52 degrees centigrade. Contact with eyes causes severe irritation and burns. Concentrated sulfuric acid is less effective because it oxidizes HBr to bromine: Anhydrous hydrogen bromide can also be produced on a small scale by thermolysis of triphenylphosphonium bromide in refluxing xylene. Information on this page: (S.F.). Occurrence/Uses: Hydrogen bromide is used in the synthesis of organic chemicals, for dissolving certain ores (metal extraction), in the manufacture of bromides, and as an alkylation (synthesis of high molecular weight hydrocarbons from lower molecular weight hydrocarbons) catalyst. It is corrosive and if heated or exposed to fire under pressure can cause it to explode. If large quantities of this chemical are inhaled, the exposed person should be moved to fresh air immediately. Then repair the leak. [9], Hydrogen bromide prepared by the above methods can be contaminated with Br2, which can be removed by passing the gas through a solution of phenol at room temperature in tetrachloromethane or other suitable solvent (producing 2,4,6-tribromophenol and generating more HBr in the process) or through copper turnings or copper gauze at high temperature.[14].
