摘　　要：为了提高7-氨基-4,6-二硝基苯并氧化呋咱(ADNBF)的合成收率,以3-硝基苯胺为起始原料,经乙酰化、硝化﹑环合三步反应得到ADNBF,三步总质量收率为75%。采用核磁共振光谱、质谱、红外光谱表征了目标化合物的结构;探讨了硝化反应的影响因素,确定了适宜的硝化反应条件。结果表明,当反应温度为70℃,反应时间为0.5 h,3-硝基乙酰苯胺与发烟硝酸量比为1∶4时,硝化质量收率89%;ADNBF安全性能优于三硝基甲苯(TNT),爆炸性能与1,3,5-三氨基2,4,6-三硝基苯(TATB)接近。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).
