Abstract:

High heating rate thermoylsis studies of energetic materials using rapid-scan Fourier transform infrared spectroscopy as the diagnostic technique have yielded considerable information on the origins of the pressure dependence of the process and structurepropertyreactivity relationships. The pressure dependence of the observed gas products up to 1000 psi was shown for the first time to originate from heterogeneous gascondensed phase reactions. The formation of NH3 from alkylammonium nitrate salts occurs only if the OH ratio is less than one. The thermochemistry of cyclic and acyclic nitramines is shown to be different in the condensed phase as a result of the different global molecular shapes. Hydrogen bonding as a stabilizing feature in the impact sensitivity of an energetic material was shown to be overridden by the presence of energetic functional groups. Keywords Thermal decomposition, Infrared spectroscopy, Pressure effects, Gas analysis, Impact sensitivity, Energetic materials.
