Structure/Property/Reactivity Relations Among Nitramine and Other Energetic Materials.
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 structure/property/reactivity relationships. The pressure dependence of the observed gas products up to 1000 psi was shown for the first time to originate from heterogeneous gas/condensed phase reactions. The formation of NH3 from alkylammonium nitrate salts occurs only if the O/H 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.
