Abstract 1-(2-azidoethyl) pyrrolidine (AZEP) was prepared in our laboratory and its density and dynamic viscosity were measured over the temperature range from 273.15 K to 373.15 K. Its vapor pressure were determined in the range of (311.75–418.15) K using a dynamic method. The experimental data were analyzed by regression analysis using Origin 8.5 simulation software. The density data were fitted to a first order polynomial and the viscosity data were regressed to the Vogel- Fulcher-Tammann equation. The results of vapor pressure were fitted to Antoine equation and Clapeyron equation. What's more, melting point was measured using Differential Scanning Calorimetry (DSC) and the melting point was −132.36 °C. Flash point was also determined using closed cup flash point tester and the value was 43.9 °C.

液体推进剂的密度、粘度、蒸气压、熔点和闪点：1-(2-叠氮乙基)吡咯烷

摘要 本实验室制备了 1-(2-叠氮乙基)吡咯烷 (AZEP)，并在 273.15 K 至 373.15 K 的温度范围内测量了其密度和动态粘度。其蒸气压在 (311.75-418.15) 范围内测定K 使用动态方法。实验数据采用Origin 8.5仿真软件进行回归分析。密度数据拟合为一阶多项式，粘度数据回归到 Vogel-Fulcher-Tammann 方程。蒸气压的结果符合Antoine方程和Clapeyron方程。更重要的是，熔点是使用差示扫描量热法（DSC）测量的，熔点为-132.36°C。闪点也使用闭杯闪点测试仪测定，值为43.9°C。
