原始语种摘要: The thermal decomposition of 2, 4, 6, 8, 10, 12-hexanitro-2, 4, 6, 8, 10, 12-hexaazaisowurtzitane (CL-20) is examined via a self-modified dynamic vacuum stability test at temperature intervals of 130–170 °C. The p versus t curves indicate the multistep thermal decomposition of CL-20 and its autocatalytic behavior. The reaction rate constant k is 3.07 × 10−8, 9.61 × 10−8, 27.25 × 10−8, 133.31 × 10−8, and 387.94 × 10−8 s−1 at 130, 140, 150, 160, and 170 °C, respectively. The polymorphic transformation of CL-20 and certain products may affect kinetic output. The activation energy is 182.5 kJ mol−1, which shows good agreement with previously published results. The storage life of CL-20 at 50, 70, 90, 110, and 130 °C...
