偶氮呋咱和氧化偶氮呋咱的合成及表征

Synthesis and characterization of azofurazan and azoxyfurazan

介绍了高能材料二氨基偶氮呋咱(DAAF)、二氨基氧化偶氮呋咱(DAOAF)及二硝基氧化偶氮呋咱(DNOAF)的合成。其中,采用新型氧化剂制备DAAF,得率提高至65.60%。通过DSC-TG、元素分析、IR、1H NMR和MS等方法,对其结构进行了鉴定,并进行了常规的感度测试。感度数据表明,无氢炸药DNOAF的摩擦感度较大,与C-12相当,而DAAF和DAOAF为低感度炸药。

The synthesis of high energy materials （HEMs） such as 3,3＇ -diamino-4,4＇ -azofurazan （ DAAF）, 3,3＇ -diamino-4, 4＇ -azoxyfurazan （ DAOAF ） and 3,3＇ -dinitro-4,4＇ -azoxyfurazan （DNOAF） was introduced, and the productivity of the prepared DAAF by using a new oxidant can reach 65.60%. The product structure was evaluated by DSC-TG elemental analysis, IR, ^1 H NMR and MS methods, moreover the sensitivity were normally measured. The results show that the sensitivity of DNOAF explosive is high, which is equivalent to that of C-12, but DAAF and DAOAF explosive have low sensitivity.
