Opis:: The results of systematic multinuclear NMR studies of 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitro-1,3,5-triazacyclohexane (RDX), 1,3,5,7-tetranitro-1,3,5, 7-tetraazacyclooctane (HMX) and 3-nitro-1,2,4-triazol-5-one (NTO) are presented. For comparison of interactions between the analytes and the solvents, experiments in both deuterated DMSO and CDCl3 (where possible) were performed. Complete assignment of the resonance signals for the compounds investigated are presented. Analysis of the high resolution NTO spectra leads to new conclusions about the different reactivities of the N-H protons. The results can be used for many analytical purposes, such as solvent matching for extracting traces of explosives, controlling the purity of various samples etc.

Gurney model
Opis:: Monolithic nitrocellulose and cellulose composites (NC-C) were obtained by cross-linking a mixture of nitrocellulose with cellulose using hexamethylene diisocyanate (HDI). They were incorporated into a model reactive armour. An X-ray technique was used to examine the infuence of the cellulose content on the accelerating ability of the gaseous reaction products of the composites. The modifed Gurney model was used to simulate the process of driving steel plates in the reactive armour after jet impact. Formulae for the determination of the time-space characteristics of the plates’ movement were derived. The results of the X-ray recording of the plates driven by the explosion products of monolithic nitrocellulose and cellulose composites (NC-C) were used for the verifcation of the model.

Opis:: This paper reports measured explosive properties of 4,4’,5,5’-tetranitro-2,2’-bi-1H-imidazole dihydrate (TNBI•2H2O). Non-isothermal kinetics analysis, calorimetric measurements, detonability tests, small-scale shock reactivity tests (SSRT), detonation velocity measurements and cylinder tests were performed. The results of the cylinder tests were used to determine the acceleration ability of TNBI•2H2O. Some experiments were conducted also with TNT, NTO, FOX-7 and RDX. Our experimental studies have shown that TNBI•2H2O is a thermodynamically stable compound, surpassing TNT with regard to its energetic and detonation parameters. The results of the SSRT indicate that this material has better performance in small charges than RDX, FOX-7 and NTO.
