flavianic acid hydrate - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | used as organic synthesis intermediate, organic alkali precipitant, amino acid reagent. This product can interact with more than 50 metal ions, but only precipitate with zirconium and lead in acidic solution. It has the advantages of strong selectivity and high sensitivity for the determination of zirconium. |
| production method | is obtained by sulfonation and nitration of α-naphthol. 200g of 25% fuming sulfuric acid was slowly added into 50g of α-naphthol, stirred and dissolved, and reacted at 125 ℃ for 1h. After the reaction is completed, cool, mix with 500g of crushed ice, and filter. 120g of concentrated nitric acid with a relative density of 1.40 was added to the filtrate and heated at 50 ℃ for 1.5h. The reactants are placed at room temperature for 12h, filtered, recrystallized with dilute hydrochloric acid, and dried to obtain the finished product. |
