| Abstract: | 2,4- Dinitrotoluene was used as the main material to synthesize 2,4- difluorotoluene in the presence of AHF. The mole ratio of Na NO2 and 2,4- diaminotoluene was 1. 3. Reaction temperature of Schiemann reaction was- 10 - 7 ℃. The decomposition temperature was 40 ℃. The recovery of the final product was 86%. |
