Thermal decomposition of triacetone triperoxide by differential scanning calorimetry



Triacetone triperoxide (TATP) is an organic peroxide that is sensitive and can be readily synthesized, and is thus used as an explosive. In this study, three sulfuric acid (H2SO4) concentrations (1, 9, and 18 M) were used to synthesize TATP. The higher concentrations of H2SO4 resulted in higher concentrations and swift production of TATP. Each combination was compounded with different thermal hazard characteristics. The thermal decomposition of TATP was studied through differential scanning calorimetry (DSC) to obtain exothermic onset temperature (T0), heat of decomposition (ΔHd), and maximum temperature during the overall reaction (Tmax). The apparent activation energy (Ea) was calculated using the Kissinger method and the Ozawa method. Gas chromatography and mass spectrometry were employed to confirm the synthesized TATP. This study used DSC to evaluate the thermal decomposition and analyze the efficiency of fire-extinguishing reagents. Results showed that different inhibiting reagents had different efficiency levels for TATP. Thus, inhibiting reagents can be expected to diminish the damage caused by TATP explosions. In this study, the mechanism of TATP synthesis was investigated.
