Use | bromoacetic acid is a raw material for the preparation of ω-bromo-2, 4-dichloroacetophenone, intermediates of triazole fungicides such as propiconazole. intermediates in organic synthesis. Used in the production of pesticides and pharmaceuticals. Its esters can also be produced. for organic synthesis |
production method | 1. Acetic acid is used as a raw material, and bromine is added dropwise in the presence of pyridine for reaction. 2. By the reaction of chloroacetic acid and hydrobromic acid. Derived from the reaction of glycolic acid with hydrobromic acid. obtained by reaction of bromine with pyridine as a solvent in a mixture of acetic anhydride and anhydrous acetic acid. Reaction equation: CH3COOH Br2 → BrCH2COOH HBr |
