摘　　要：为制备新型富氮杂环含能化合物,以5-氰基-1-(1H-1,2,4-三唑-3-基)-1H-四唑(1)为原料,经偕胺肟化、重氮化、取代及亲电加成等步骤,合成一种以酰胺键桥联的富氮含能化合物1-羟基-N-(1H-1,2,4-三唑-5-基)-1H-四唑-5-甲酰胺(3);利用核磁共振(NMR)、傅里叶红外光谱(FT-IR)、元素分析(EA)等方法对化合物3进行了结构表征,并通过单晶X-射线衍射分析(SC-XRD)进一步确定了其结构;利用差示扫描量热(DSC)和热重(TG)方法研究了化合物3的热分解过程。结果表明,化合物3初始分解温度为265℃,爆速为8017 m·s^(-1),爆压为23.1 GPa,撞击感度为20 J,摩擦感度为288 N。In order to explore novel nitrogen-rich heterocyclic energetic compounds,an amide bridged energetic compound 1-hydroxy-N-(1H-1,2,4-triazol-3-yl)-1H-tetrazole-5-carboxamide was synthesized from 5-cyano-1-(1H-1,2,4-triazol-5-yl)-1H-tetrazole through several steps involving amidoximation,diazotization,substitution and electrophilic addition.Its structure was fully char-acterized by nuclear magnetic resonance(NMR),Fourier transform infrared spectroscopy(FT-IR)and elemental analysis(EA).X-ray diffraction analysis(SC-XRD)was adopted to further confirm its structure;its thermal decomposition process was studied by differential scanning calorimetry(DSC)and thermogravimetry(TG).The compound has a high onset decomposition tempera-ture of 265℃and shows good properties with detonation velocity of 8017 m·s^(-1),and detonation pressure of 23.1 GPa,impact sensitivity of 20 J,and friction sensitivity of 288 N.
