Determination of the Vapor Density of Triacetone Triperoxide (TATP) Using a Gas Chromatography Headspace Technique
نویسندگان
چکیده
Using a GC headspace measurement technique, the vapor pressure of TATP was determined over the temperature range 12 to 60 8C. 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 10 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)1⁄4 19.791 5708/T(K). Its heat of sublimation has been calculated as 109 kJ/mol.
