✦ Synopsis

Rapid-scan infrared spectra with a temporal resolution of 0.2 s of the first observed gas products, several mm from the surface of 34 fast heated (100-130K s -~) energetic materials, were compared over a pressure range of 1-1000 psi Ar. The first observed gas products were strongly dependent on the pressure for many of the compounds and exhibited three distinct zones of products. This behavior is consistent with the model for HMX combustion. A second category of compounds, which was further subdivided three ways, contains compounds that lack the three zone behavior and were much less pressure dependent. Most of the patterns are best explained by the relative importance of heterogeneous gas-phase/condensed-phase reactions. For strongly pressure dependent compounds these heterophase reactions become progressively more important with increasing pressure.
