| Abstract: | 2-Fluoro-5-nitrobenzonitrile was prepared from 2-Fluorobenzonitrile.The reaction condition was mild and the process was easy to be controlled.The outcome was tested by GC and calculated quantitatively,it turned out that both the yield and the conversion rate could be up to 100%under the optimal conditions that n(2-Fluorobenzonitrile):n(potassium nitrate) = 1:1,50 mL sulfuric acid used as solvent and reacted at 20℃for 1.5 h.The repeated experiments under optimal conditions showed that the preparation method was easy to be controlled and good in repeatability. |
