摘要 介绍了新型炸药N,N'-双(3,5-二氯-2,4,6-三硝基苯基)-3,4-二氨基呋咱的合成.在碱性介质中,二氯乙二肟(Ⅰ)与3,5-二氯苯胺反应,生成化合物N,N'-二(3,5-二氯苯基)二氨基乙二肟(Ⅱ),收率66%.(Ⅱ)在乙二醇的氢氧化钠溶液中高温脱水,制得化合物N,N'-双(3,5-二氯苯基)-3,4-二氨基呋咱(Ⅲ),收率64%.(Ⅲ)在70℃下于硝酸(w(HNO3)=85%)中硝化3 h,得到目标化合物N,N'-双(3,5-二氯-2,4,6-三硝基苯基)-3,4-二氨基呋咱(Ⅳ),熔点124~125℃,收率82.7%.通过红外光谱、核磁共振、质谱及元素分析确定了3种化合物的结构. The synthesis of a novel explosive-N, N'-bis(3, 5-dichloro 2, 4, 6-trinitrophenyl)-3, 4-diaminofurazan(BCNDAF) is described in detail. The condensation of dichloroglyoxime ( Ⅰ ) with 3, 5 chloroaniline in basic media gives N, N'-bis(3, 5-dichlorophenyl)diaminoglyxime ( Ⅱ) with a yield of 66%. ( Ⅱ ) can then be converted to N, N'-bis(3, 5-dichlorophenyl)-3, 4-diaminofurazan ( Ⅲ ) with a yield of 64 % via dehydration in a NaOH/HOCH2CH2OH solution at high temperature. The title corn pound ( Ⅳ) is obtained in 82.7 % yield by the nitration of ( Ⅲ) with nitric acid ( ω (HNO3) - 85 % ) at 70℃ for 3 h. The melting point of ( Ⅳ )is 124-125 ℃. The structures of N, N'-bis(3, 5-dichloro-2, 4, 6-trinitrophenyl)-3, 4-diaminofurazan and its two intermediates have been determined by IR, IHNMR, MS and elemental analysis.
