| Abstract: | A new derivative of
3-nitro-1,2,4-triazol-5-one (NTO, 2), viz.,
2,4-dihydro-2,4,5-trinitro-3H-1,2,4-triazole-3-one (DTNTO, 3) has been obtained by nitration of NTO synthesized during this
work using fuming nitric acid and acetic anhydride. The title compound 2 was
obtained from 2,4-dihydro-3H-1, 2,4-triazol-3-one (TO, 1). The newly
synthesized DTNTO has been characterized by elemental analysis, IR, 1H
and 13C NMR. The DTA and DSC of (3) showed exothermic decomposition with peak temperature (Tmax) of 264oC. TG
showed 61% weight loss for 3 in the
temperature range of
194-264oC. 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. |
