摘要:
以二氨基呋咱(DAF)为起始原料,利用Caro′s acid氧化得到3,3′-二氨基-4,4′-氧化偶氮呋咱(DAOAF),在水介质中,用Zn粉还原得到目标化合物3,3′-二氨基-4,4′-偶氮呋咱(DAAzF),总收率为92%,纯度98.6%(HPLC)。用IR、1HNMR、13CNMR及元素分析等方法对DAAzF和中间体结构进行了表征。采用卡斯特落锤法、DSC及TG-DTG对DAAzF的性能进行了研究。结果表明,其撞击感度和摩擦感度均为0,起始分解温度为281.7℃, 热分解DSC曲线峰温为320.3℃。表明DAAzF具有良好的热稳定性,机械感度较低,可作为钝感炸药的候选物。
Abstract:

The synthetic method for 3,3-diamino-4,4-azofurazan (DAAzF) with a total yield of 92% and purify of 98.6%was obtained using 3,4-diaminofurazan (DAF) as starting material, through 3,3-diamino-4-axoxyfurazan by the oxidation ofCaros acid and deoxidization of Zn in water.DAAzF andits intermediates were characterized by IR, 1HNMR, 13CNMRand element analysis. The properties of DAAzF were studied by Custer hammermethod, DSC and TGDTG. The results show that theimpact sensitivity and friction sensitivity are 0. Its initial decompositiontemperature is 281.7. The peak temperature of DSCcurve thermal decomposition reaction in DSC curve is 320.3, showing that DAAzF was a candidate insensitive explosive withlower mechanical sensitivity and good thermostability.
