摘　　要：以乙二醛为原料,经过中间体二（4-氨基呋咱基-3-氧化偶氮基）偶氮呋咱（ADAAF）,合成了高能材料二（4-硝氨基呋咱基-3-氧化偶氮基）偶氮呋咱（ADNAAF）。用红外、核磁、质谱等表征了其结构。分析了在溴酸钾和冰乙酸的氧化体系下合成中间体ADAAF的影响因素,确定最佳工艺条件为：反应温度50℃,反应时间16 h,冰乙酸与3,3＇-二氨基-4,4＇-氧化偶氮呋咱（DAOAF）摩尔比为68∶1,收率为58.5%。采用差示扫描量热法和热重分析研究了ADNAAF和ADAAF的热性能。结果表明,ADAAF的分解温度为267.18℃,热重变化范围50-500℃,共失重90.91%;ADNAAF的分解温度为114.81℃,热重变化范围70-500℃,共失重100%。对ADNAAF的爆轰性能进行了理论预测,爆速,爆压分别为9140 m·s^-1和38 GPa,是一种具有潜在应用价值的高能量密度化合物。The high energy compounds bis[4-nitraminofurazanyl-3-azoxy]azofurazan（ADNAAF） was synthesized from bis[4-aminofurazanyl-3-azoxy]azofurazan（ADAAF） using glyoxal as starting material.The structures of ADNAAF and ADAAF were characterized by IR,NMR and MS.With KBrO3 and glacial acetic acid as oxidation system,the factors affecting the synthesis of ADAAF were studied.The optimum reaction conditions were found to be as follows：the reaction temperature 50 ℃,reaction time 16 h,and n（CH3COOH）：n（DAOAF） =68：1,with a yield of 58.5%.The thermal properties of ANDAAF and ADAAF were studied by differential scanning calorimetry and thermogravimetry analysis.Results show that the initial decomposition temperature of ADAAF and ADNAAF are 267.18 ℃ and 114.81 ℃,respectively,and the mass loss of ADAAF due to overall reaction（50-500℃） is 90.91%and ADNAAF（70-500 ℃） is 100%.The detonation performances of ADNAAF were estimated by Gaussian 03.The detonation velocity of ADNAAF is 9140 m · s^-3 and detonation pressure is 38 GPa,which indicates that ADNAAF is a high energy density compound with potential application value.
