Thermal decomposition kinetics and mechanism of the high-energetic material 5,7-diamino-4,6-dinitrobenzenfuroxan (CL-14) were determined by differential scanning calorimetry (DSC), rapid scanning Fourier transform infrared spectroscopy, and simultaneous thermogravimetric and DSC analyses, coupled with FT-IR and mass spectroscopy. To evaluate the thermal safety of 5,7-diamino-4,6-dinitrobenzenfuroxan (CL-14), its specific heat capacity ( C) was measured by DSC, and thermal conductivity ( λ) was estimated. Kinetic parameters and heat of exothermic decomposition reaction of CL-14 were obtained by analysis of DSC curves. Kinetic parameters used to evaluate the thermal safety of CL-14, such as self-accelerating decomposition temperature ( T), critical temperature of thermal explosion ( T) and impact sensitivity ( H), were obtained. Results showed that for CL-14, T = 282.0 °C and T = 307.9 °C, whereas H = 39.79 cm, revealing that CL-14 had better thermal safety and heat resistance than HMX, RDX and GNTO. [ABSTRACT FROM AUTHOR]
