Abstract
Taking 4-chloro-2-nitroaniline as primary material,7-chloro-4,6-dinitro-benzfuroxan was synthesized by the process of oxidation,cyclization,nitration and rearrangement.Its structure was characterized by IR,NMR and elemental analysis.The effect of the nitration reaction temperature and 5-chlorobenzfuroxan/nitric acid mole ratio on the yield was studied.The best condition of nitration reaction were reaction temperature,60℃;5-chlorobenzfuroxan/nitric acid mole ratio,1∶10.The yield is 39%.
