Hydrogen bromide

A colorless gas, it dissolves in water, forming hydrobromic acid, which is saturated at 68.85% HBr by weight at room temperature.

Hydrogen bromide and hydrobromic acid are important reagents in the production of organobromine compounds.

Related free radical additions to allyl chloride and styrene give 1-bromo-3-chloropropane and phenylethylbromide, respectively.

The stereochemistry of this type of addition is usually anti: Also, HBr adds epoxides and lactones, resulting in ring-opening.

[11] 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.

E.g. water Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazard COR: Corrosive; strong acid or base. E.g. sulfuric acid, potassium hydroxide
