Synthesis Hydrobromic acid can be prepared in the laboratory via the reaction of Br2, SO2, and water. Br2 + SO2 + 2 H2O 鈫?H2SO4 + 2 HBr More typically laboratory preparations involve the production of anhydrous HBr, which is then dissolved in water. Hydrobromic acid has commonly been prepared industrially by reacting bromine with either sulfur or phosphorus and water. However, it can also be produced electrolytically.[3] It can also be prepared by treating bromides with non-oxidising acids like phosphoric or acetic acids. Alternatively the acid can be prepared with dilute (5.8M) sulfuric acid and potassium bromide: H2SO4 + KBr 鈫?KHSO4 + HBr Using more concentrated sulfuric acid or allowing the reaction solution to exceed 75 掳C further oxidizes HBr to bromine gas. The acid is further purified by filtering out the KHSO4 and by distilling off the water until the solution reaches an azeotrope (鈮?126 掳C at 760 torr). The yield is approximately 85%. Hydrobromic acid is available commercially in various concentrations and purities.Hydrobromic Acid 48% manufacturers website:http://www.rixingxincai.com/pharmaceutical-intermediates/hydrobromic-acid-48/
