2-AMINO-5-FLUOROPHENOL - Reference Information
| introduction | 2-amino-5-fluorophenol is an organic intermediate, which can be prepared from 2, 4-difluoroaniline in one step. 2, 4-difluoroaniline can be used to prepare the intermediate 7-fluoro-6-amino-2H-1, 4-benzoxazine-3 (4H)-one of propargeneflumine. |
| preparation method | a certain amount of 2,4-difluoroaniline, water and potassium hydroxide are successively put into the reaction kettle, the temperature naturally rises to 50-80 degrees, the temperature is kept at 50-80 degrees for about 4-5 hours, the temperature is kept at 60 minutes after adding, and the sampling is less than 0.5%. After sampling is qualified, add a certain amount of hydrochloric acid, the product is added and the water is azeotropic, stirred evenly, heated and heated, and the product is steamed out by steam distillation; after distillation, 2-amino -5-fluorophenol is obtained. |
