Sažetak
TNAZ (1, 3, 3-trinitroazetidine), a relatively new explosive material that is of considerable interest to the energetic materials community, was first prepared by Archibald and co-workers in 1990. This four-member ring explosive is interesting for the energetic materials community for several reasons: (a) it has density and detonation characteristics nearly that of standard high explosive octogen ; (b) it melts without decomposition at about 100 oC making its melt casting possible ; (c) it has oxygen balance greater than that of octogen which results in high detonation products heat and temperature. These characteristics make TNAZ to be considered as a replacement for the most powerful high explosive octogen. Thermal behaviour of TNAZ was studied in this work by using differential scanning calorimetry (DSC), differential thermal analysis (DTA), and thermogravimetryc analysis (TGA). It was found out that TNAZ is thermally more stable than hexogen, but less stable than octogen and trinitrotoluene. The reactions of intensive thermal decomposition start at 183230 oC, depending on heating rate, while the first exothermic reaction was observed at 178 oC. Detonation properties of TNAZ were predicted theoretically using an own computer program, named EXPLO5, based on the chemical equilibrium and stady-state model of detonation, and the Becker-Kistiakowsky-Wilson equation of state of gaseous detonation products. It was found out that TNAZ has detonation velocity and pressure nearly that of the most powerful standard high explosive octogen, and higher than that of commonly used high explosives (hexogen, pentrit, trinitrotoluene etc.). It was also found out that TNAZ has the detonation temperature and the detonation heat greater than that of any other high explosive considered, making TNAZ very attractive as an ingredient in composite explosives.
