The Chemical Micromechanism of Energetic Material Initiation
Original language description
The paper presents a brief survey of available results obtained from the studies of the initiation micromechanisms of mainly organic energetic materials (EMs) from the viewpoint of physical organic chemistry, with attention being paid to experimental results. It is stated here that chemical micromechanisms of the primary fission processes of the EM molecules in the “normal” initiation by mechanical stimuli (inclusive of the detonation course) and an electric spark should be the same as in the case of their low-temperature thermal decomposition. In this connection also super-initiation is mentioned, in which primary fissions should correspond to those in high-temperature thermal decomposition. Experimental methods for the probable reaction centers (chemical hot spots) found in the EMs molecules are discussed. Concerning the thermochemical aspects of the initiation reactivity, the application of the enthalpies of formation (or heats of combustion) results in less ambiguous relations with EM sensitivity in comparison to the hitherto widely used performance of these compounds. This new thermochemical approach might be applied to assess the possible primary fragmentation processes of macromolecular binders in the initiation of the plastic bonded explosives.
