碩士 === 雲林科技大學 === 環境與安全工程系碩士班 === 98 === Triacetone triperoxid (TATP) is simple synthesize and sensitive used as an explosive. Three sulfuric acid (H2SO4) concentrations (1 M, 9 M, 18 M) were used to synthesize TATP. The higher concentration of H2SO4 would produced higher concentration and faster produced of TATP. Each combination was compounded with different thermal hazard characteristics. Differential scanning calorimetry (DSC) was used to scan the thermal decomposition of TATP, which obtain exothermic onset temperature (T0), heat of decomposition (ΔHd) and maximum temperature during overall reaction (Tmax). Activation energy (Ea) were calculated by Kissinger method and Ozawa method. Gas chromatography and mass spectrometry (GC/MS) were employed to exactly affirm the synthesized TATP. This study used differential scanning calorimetry (DSC) to evaluate thermal decomposition and to analyze the efficiency of fire-extinguishing reagents. Results showed the efficiency of various inhibiting reagents on TATP were distinct and distinguished. Thus, diminished damage by TATP explosion is expected. In this study, the mechanism of synthesize TATP is described.
