采用热重分析（ TG），差示扫描量热法（ DSC），固体原位池/红外和质谱（直接进样和热裂解-色谱-质谱联用方式）研究了偶氮四唑胍（ GZT）的热分解行为，凝聚相产物和气相产物的变化，提出了 GZT的热分解机理。结果表明，GZT 分解失重的第一阶段由偶氮四唑的放热分解反应和胍分解的吸热过程构成。在单独热作用下，GZT 首先发生质子转移形成偶氮四唑和胍，然后分别分解。偶氮四唑的四唑环经过开环反应，可能形成中间产物叠氮四唑（ CHN7），最终生成三聚氰胺和叠氮铵等高沸点物质。在离子源轰击作用下除了四唑环开环解离外，C-N azo也会发生断裂，进而裂解。

The thermal behavior of guanidinium azotetrazolate( GZT)was studied using the thermogravimetry and differential scan-ning calorimetry. The thermal decomposition mechanism of GZT was proposed based on the investigation of products in con-densed and gas phases by the combination techniques of solid in situ cell with the rapid-scan Fourier transform infrared spectrosco-py and pyrolysis-gas-chromatography-mass-spectrometry( Py-GC-MS). Results show the first mass loss process of GTZ includes the exothermic decomposition reaction of azotetrazolate and the endothermic decomposition reaction of guanidinium. Under heat-ing,the intermediate product tetrazoleazide( CHN7 )may forme through the ring-opening reaction of tetrazole on the azotetrazo-late molecular and the ultimate products are high boiling point materials:melamine and ammonium azide. Under the bombard-ment of ion source,the bond C-Nazo on azotetrazolate molecular also split and dissociate in sequence.
