【 摘 要 】

Differential Scanning Calorimetry (DSC), Thermogravimetry(TG) and vent sizing package 2 (VSP2) were performed to understand thermal behavior and decomposition kinetics of triacetone triperoxide (TATP) under non-isothermal and adiabatic conditions, respectively. Then the maximum self-heating rate [(dT/dt)max], maximum pressure rise rate[(dP/dt)max] were acquired. DSC studies revealed a coupling phenomenon of decomposition reaction and phase transition. Based on the DSC data, the thermal decomposition kinetic parameters were worked out and compared through the Friedman and ASTM E698 methods. The results indicated that Heat of decomposition (ΔHd) was extraordinary large even up to 2700 Jg-1 for which recrystallized with methanol merely. The activation energy of which used methanol to recrystallize was 155.5kJ/mol by (ASTM) E-698 methods. By Friedman method Linear regression was able to reach a high enough level when the reaction progress (α) was between 0.1-0.9. The results can be used to calculate the optimal parameters for processing a safer design and establish the database of TATP for loss prevention protocol.
