| مستخلص: |
4-(2,2,2-trinitroethyl)-2,6,8,10,12-pentanitro-2,4,6,8,10,12-hexaazaisowurtzitane exhibits high detonation performance, acceptable sensitivity and good thermal stability. The decomposition kinetic models for the compound were established on the basis of DSC and ARC results. The estimated thermal safety parameters can be applied to evaluate the hazards associated to it. The results show it prospective for potential applications as a novel high energy density compound. The physicochemical and energetic properties of 4-(2,2,2-trinitroethyl)-2,6,8,10,12-pentanitro-2,4,6,8,10,12-hexaazaisowurtzitane (1) are investigated. The energetic cage compound exhibits detonation properties comparable to those of HMX, and its impact sensitivity is higher than that of ε-CL-20. It shows a significantly higher thermal stability with a decomposition temperature of 227.6 °C than those of the other trinitromethyl-substituted energetic compounds. Its thermal behavior is further investigated using differential scanning calorimetry and accelerating rate calorimetry. The non-isothermal and adiabatic decomposition reaction kinetics of compound 1 are studied, and its thermal safety is evaluated using different criteria including the self-accelerating decomposition temperature, critical temperature of thermal explosion, and five-second delay exploding point.
