Possibilities of the 13C NMR Spectroscopy application in the Study of Initiation Reactivity of Highly Thermally Stable Polynitro Arenes
The paper is focused on application of l3C NMR chemical shift, δc, in the study of initiation reactivity of 1,3- dinitrobenzene (1, 3-DNB), 1, 3, 5-trinitrobenzene (TNB), 2, 2, 4, 4, 6, 6-hexanitrobiphenyl (HNB), 2, 2, 4, 4, 4 6, 6 6-dodecanitro-l, 3, l, l quaterphenyl (DODECA) and 1, 4, 5, 8-tetranitronaphthalene (TENN). In the nature of the characteristics of the studied polynitro arenes reactivity, activation energies of their thermal decomposition, their thermostability thresholds, ignition temperatures, onsets of their exothermic decomposition, their sensitivities to impact and electric spark and their heats of explosion are taken. The relationships found between the δc values and mentioned characteristics make it possible to specify reaction centres in molecules of the studied arenes. It is stated that cumulation of trintrophenylene building units over three in the molecule leads to decreasing thermal stability in the resulting polynitro arene
