3,4-dibromobenzoic acid - Reference Information
| Use | 3, 4-dibromobenzoic acid is a colorless crystal with a boiling point of 276 °c at room temperature. As a pharmaceutical intermediate, it is widely used in the molding process of high molecular plastics, as a special plasticizer, a compound or a mixture of compounds that is added to a polymeric resin to provide flexibility and toughness. |
| preparation | toluene was nitrated, para-product was taken and reduced with Fe/HCl to obtain p-aminotoluene, this product was directly brominated to give 1-amino -2, 5-dibromo-4-methylbenzene, then reacted with NaNO2/HCl to obtain a diazonium salt, and then reduced with H2PO3 to give 3, 4-dibromotoluene, finally, potassium permanganate was oxidized to give 3, 4-dibromobenzoic acid. |
