Yield:364-74-9 83%
Reaction Conditions:
with sulfuric acid;potassium nitrate at 5;Large scale;
Steps:
1.1; 2.1 (1)nitration reaction
1400 g of p-difluorobenzene and 5800 mL of sulfuric acid were added to the reaction vessel, and the temperature was controlled at about 5 °C. 1450 g of potassium nitrate was added in portions.After the reaction is over, the GC tracks,Until the reaction is completed. After completion of the reaction, ice water was analyzed by water and suction filtered to give a white solid 2,5-difluoronitrobenzene, 1620 g, content 99%, yield 83%.
