摘要
以乙酰乙酸乙酯为原材料制备了氧化呋咱类关键中间体4-氨基-3-叠氮羰基氧化呋咱,以此为前体合成了二氨基偶氮二氧化呋咱(DAAFO)。采用元素分析、红外、质谱和热分析等方法对上述物质进行了表征。结果表明,4-氨基-3-叠氮羰基氧化呋咱感度略高于二氨基呋咱、HMX;二氨基偶氮二氧化呋咱放热分解峰温为208.17℃,低于二氨基偶氮二呋咱和二氨基氧化偶氮二呋咱。
3,3 '-Diamino-4,4'-azofuroxan (DAAFO) was synthesized by a two-step process, with 4-amino-3-azidocarbonylfuroxan as precursor which was synthesized by a three-step process with ethyl acetoacetate as starting material. The DAAFO and mediate products were characterized by DSC-TG, elemental analysis,IR and MS. And the sensitivity and DSC analysis of DAAFO were carried out and compared. The results show that 4-amino-3-azidocarbonylfuroxan is more sensitive than diaminofurazan and HMX. The peak decomposition temperature of DAAFO is 208. 17 ℃ , lower than that of 3,3'-diamino-4,4'-azofurazan (DAAF) and 3,3'-diamino-4,4'-azoxyfurazan ( DAOAF).
