- W2185028343 abstract "DTNTO has been characterized by elemental analysis, IR, 1 H and 13 C NMR. The DTA and DSC of (3) showed exothermic decomposition with peak temperature (Tmax) of 264 o C. TG showed 61% weight loss for 3 in the temperature range of 194-264 o C. The sensitivity data obtained for the newly synthesized compound indicates its relatively high susceptibility towards external stimuli (Impact height, h50% explosion 80 cm, 3 kg drop weight and friction insensitive up to 25 kg) in comparison to NTO (h50% >100 cm, 3 kg drop weight and friction insensitive up to 36 kg). The theoretically predicted performance of compound 3 in terms of velocity of detonation (8.79 km/s) is intermediate to that of NTO (8.75 km/s) and RDX (8.93 km/s). The calculated CJ pressure and sound intensity for DTNTO are found superior in comparison to benchmark high explosives RDX and HMX. Its positive oxygen balance is an attractive feature from the point of view of its application as an eco-friendly oxidizer in propellant formulations. IPC Code:C06B Today’s benchmark high explosives such as 1,3,5trinitro-1,3,5-triazacyclohexane (RDX) and 1,3,5,7tetranitro-1,3,5,7-tetraazacyclooctane (HMX) are beset with the problem of high sensitivity to impact and shock 1 . Attempts are on to realize molecules, which deliver high performance, but are relatively more insensitive despite belonging to UN 1.1 hazard division to permit safe handling. Realization of such explosives can lead to logistic advantages like, reduction of quantity distances between storage sites, decreased battlefield vulnerability of armoured vehicles and personnel as well as increased capacity to carry a large quantity of ordnance. Such attempts have led to the developments of a series of new highenergy materials (HEMs) with promising blend of insensitivity and performance 2-7 . Among the molecules of this class, 1,2,4-triazoles like 5-nitro2,4-dihydro-3H-1,2,4-triazole-3-one (NTO), 3-amino5-nitro-1,2,4-triazole (ANTA), 4,6-bis (5-amino-3" @default.
