Abstract

Using a GC headspace measurement technique, the vapor pressure of TATP was determined over the temperature range 12 to 60°C. As a check on the experimental method, TNT vapor pressure was likewise computed. Values for TNT are in excellent agreement with previous published ones. For TATP the vapor pressure was found to be ∼ 7 Pa at ambient conditions. This value translates to a factor of 104 more molecules of TATP in air than TNT at room temperature. The dependence of TATP vapor pressure on temperature can be described by the equation log10P(Pa) = 19.791 - 5708/T(K). Its heat of sublimation has been calculated as 109 kJ/mol. © 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
