ABSTRACT

Vapor pressure and enthalpy of sublimation of triacetone triperoxide (TATP) that was synthesized using two different catalysts and without recrystallization were investigated by the gas chromatography headspace technique for exploitation in designing its detection remotely or using standoff capabilities. Vapor pressures and enthalpies of sublimation were calculated from the ideal gas and Clausius-Clapeyron equation, respectively. Good linearity of these equations implies that the enthalpy of sublimation is relatively constant over the temperature range studied. The enthalpies of sublimation were found to be 71 ± 4.8 and 65 ± 6.1 kJ mol−1 for TATP catalyzed by HCl and H2SO4, respectively. Also, the vapor pressures differed considerably for the chosen catalysts across the temperature range investigated, suggesting a vapor pressure and sublimation enthalpy dependency on the choice of catalyst used. Both values are in agreement with literature-reported vapor pressure data and enthalpies of sublimation (70−109 kJ mol−1). The study showed that TATP undergoes sublimation at steady rates at approximately 293 K and above.
