在15 - 55 ℃范围内，通过气相色谱（GC）顶空技术检查了双过氧化二丙酮（DADP）和双过氧化三胺（HMTD）的蒸气特征。对2，4，6-三硝基甲苯（TNT）和三过氧化三丙酮（TATP）的蒸气压进行了平行测定。TNT和TATP的蒸气压与以前报道的结果一致。DADP的蒸气压在25 ° C下被确定为17.7Pa，这比在相同温度下的TATP高大约2.6倍。DADP的Clapeyron方程为：L_（Pa）= 35.9 - 9845.1/T（K）。根据克拉珀龙方程直线的斜率计算的升华热为81.9千焦摩尔（-1）。由于热稳定性降低导致气相分解产物，因此未测定HMTD蒸气压。
The vapor signature of diacetone diperoxide (DADP) and hexamethylene triperoxide diamine (HMTD) were examined by a gas chromatography (GC) headspace technique over the range of 15 to 55 degrees C. Parallel experiments were conducted to redetermine the vapor pressures of 2,4,6-trinitrotoluene (TNT) and triacetone triperoxide (TATP). The TNT and TATP vapor pressures were in agreement with the previously reported results. Vapor pressure of DADP was determined to be 17.7 Pa at 25 degrees C, which is approximately 2.6 times higher than TATP at the same temperature. The Clapeyron equation, relating vapor pressure and temperature, was LnP (Pa) = 35.9 - 9845.1/T (K) for DADP. Heat of sublimation, calculated from the slope of the line for the Clapeyron equation, was 81.9 kJ mole(-1). HMTD vapor pressure was not determined due to reduced thermal stability resulting in vapor phase decomposition products.
