replacement of gem-dinitro group with gemazidonitro group makes greatly reduce vapor pressure, melting point as well as the thermal decomposition temperature. The in-situ FTIR spectroscopy of ADNAZ proved the strength of nitro group decreases faster than that of azide group, and a carbonyl group (C=O) was formed at the quaternary carbon center on the azetidine skeleton during heating process.

本研究考察了 3⁃
叠氮基⁃1,3⁃二硝基氮杂
环丁烷(ADNAZ)的系统热行为,并与 1,3,3-三硝基氮杂
环丁烷(TNAZ)进行了比较。结果表明,ADNAZ 的解链温度较低,为 78 °C。ADNAZ 在大气压下的最终质量损失为 88.2%。与TNAZ相比,用对对硝基取代对对二硝基,大大降低了蒸气压、熔点和热分解温度。ADNAZ 的原位 FTIR 光谱证明硝基的强度比
