Abstract:
In order to increase the yield of 7-amino-4,6-dinitrobenzofuroxan(ADNBF),a synthetic method is explored using 3-nitroaniline as the starting materials.The ADNBF is produced in three steps of acylation,nitration and Nietzki-Dietschy cyclization with the total yield of 75%.The product is characterized by the nuclear magnetic resonance(NMR),the mass spectrometry(MS)and the infrared red(IR).The principal effects of the nitration reaction are studied,and the optimal reactive conditions are obtained.The results show that,when the reactive time is 0.5h at 70 ℃ and the ratio of 3-nitroacetanilide and fuming nitric acid is 1:4,the nitration mass yield reaches 89%.The property test shows that ADNBF is much less sensitive than trinitrotoluene(TNT)and its explosive properties is similar to 1,3,5-triarimino-2,4,6-trinitrobenzene(TATB).
