| Product | HCID 23367254 | HCID 23367254 | 91.2% |
Reaction Steps
The following reactants, 9.06 g of 4,4'-dimethoxydiphenic acid, 100 ml of glacial acetic acid and 50 g of 48% HBr were heated at reflux for 12 hours. After most of the solvent had been distilled off, water was added and the solution heated to dissolve the solid residue. The solution was decolorized twice using active charcoal and cooled to yield 7.5 g of white 4,4'-dihydroxydiphenic acid.
