Abstract
- Thermal decomposition of melted 3,4-bis(3-nitro-furazan-4-yl)furoxan (DNTF) in near adiabatic environment was first time investigated by using accelerating rate calorimeter. Based on the experimental results, the kinetic parameters of exothermic reaction of DNTF under adiabatic condition were calculated. The thermal decomposition parameters, including the initial decomposition temperature, the adiabatic temperature rise and the maximum temperature rise rate, were obtained from the thermal inertia factor. The adiabatic experiment revealed that DNTF has a relatively high initial exothermic decomposition temperature at 180.7 °C. The apparent activated energy Ea and pre-exponential factor A were calculated as 197.54 kJ mol and 7.68 × 1016 s, respectively. In addition, self-accelerating decomposition temperature and 5-s delay exploding point of DNTF were also provided, which is consistent with the data obtained by the traditional Wood's alloy bathy method.
