use | for organic synthesis. |
production method | 2,6-dinitro-4-methylaniline is dissolved in anhydrous ethanol-concentrated sulfuric acid, sodium nitrite is added under stirring, and the temperature is controlled not to exceed 20 ℃. After adding, heat up and reflux for 15min. Slightly cold, add activated carbon to decolorise, filter while hot, cool the filtrate to room temperature, pour into cold water, precipitate the product, filter, wash to neutral, and obtain coarse product. The crude product is recrystallized with benzene to obtain the finished product. |
