The systematical thermal behaviors of 3⁃azido⁃1,3⁃dinitroazetidine (ADNAZ) was investigated in this research and compared with those of 1,3,3-trinitroazetidine (TNAZ). The results showed that ADNAZ has a low melting temperature at 78 °C. The final mass loss of ADNAZ under atmospheric pressure is 88.2%. Compared to TNAZ, the 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. TG/DSC–FTIR–MS quadruple technology was applied, finding small molecular fragments from ADNAZ’s thermolysis includes H₂ (m/z = 2), H₂O (m/z = 18), CN (m/z = 26), HCN (m/z = 27), N₂ (m/z = 28), NO (m/z = 30), C₂H₂O (m/z = 42), HN₃ (m/z = 43), CO₂ (m/z = 44), and NO₂ (m/z = 46). A detailed decomposition mechanism was proposed based on the experimental results.

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叠氮基的强度下降得更快，并且在加热过程中在氮杂环丁烷骨架的季碳中心形成羰基（C = O）。应用 TG/DSC–FTIR–MS 四极杆技术，从 ADNAZ 的热解物中发现小分子片段，包括 H₂ (m/z = 2), H ₂ O (m/z = 18), CN (m/z = 26), HCN (m/z = 27), N 2 (m _/ z = 28), NO ( m/z = 30)、C ₂ H ₂ O (m/z = 42)、HN ₃ (m/z = 43)、CO ₂ (m/z = 44) 和 NO ₂ (m/z = 46) . 基于实验结果提出了详细的分解机制。
