2-Bromo-5-nitrobenzotrifluoride Use and Manufacturing
At room temperature and stirring to 260 g concentrated sulfuric acid (98percent) slowly add 120 g fuming nitric acid, dubbed nitric acid. 50-60°C to the mixed acid slowly add the product of the next step o-bromotrifluorotoluene 390 g, after adding insulation stir, GC detection has no raw materials that For the end of the reaction. Liquid, the upper organic phase washed by alkali to neutral, washed immediately after the bright yellow liquid liquid 2-bromo-5-nitro-trifluorotoluene 450.4 g, GC content: 95percent, yield: 92percent.
