Characteristics of Thermal Decomposition of Energetic Materials in a Study of their Initiation Reactivity

Popis výsledku v původním jazyce

This is a survey mainly of the author’s results which were obtained from a study of the chemical micromechanisms of energetic materials (EMs) initiation by means of knowledge about kinetics and mechanisms of the low-temperature thermal decomposition of these materials. Attention is given to the relationships between the characteristics of thermal decomposition, on the one hand, and data from the detonation, impact, friction, and electric spark sensitivities of EMs, on the other. Since the initiation reactivity of EMs is in general influenced by steric conditions and electron configuration in a reaction center of their molecules, it is possible to also study the micromechanisms of their primary chemical processes with the help of the 15N a 13C NMR chemical shifts including application of the DFT methodologies and outputs from X-ray spectroscopy; by comparing outputs of the aforementioned methods with the characteristics of the aforesaid reactivity, it is possible to specify the reaction center in a given molecule for a given type of initiation. On the basis of the results obtained, an attempt was made to explain a “high sensitivity” of epsilon-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (HNIW).
