1. The compound is easiely obtain by reacting pentaerytrit with hydrobromic acid . 2. Hydrobromic acid is one of the strongest mineral acids known.3. Hydrobromic acid is a solution of HBr in water.4. Angelic acid reacts with hydrobromic acid and bromine producing hydrochloric and hydroiodic acids, respectively. 5. It may be formed by the reaction of bismuth oxide and hydrobromic acid with the equation 6. Alcohols may likewise be converted to bromoalkanes using hydrobromic acid or phosphorus tribromide ( PBr 3 ). 7. Hydrobromic acid has commonly been prepared industrially by reacting bromine with either sulfur or phosphorus and water.8. For example, in the presence of hydrobromic acid , the dimer dissolves and bromoauric acid is formed. 9. This combination is problematic when membranes are used, because they form hydrobromic acid that can destroy the membrane. 10. It may be prepared by the reaction of osmium tetroxide with hydrobromic acid , followed by zinc and cyclopentadiene.
