Validation of Approaches (Salt Formation & Introduction of Amino Group/s) for Imparting/Improving Thermal Stability of Explosives, Part I

Abstract

AbstractThere are 4 general approaches for imparting or improving the thermal stability of explosives – ‘Salt Formation’, ‘Introduction of Amino Group/s’, ‘Introduction of Conjugation’ & ‘Condensation with a Triazole ring’ as proposed by Agrawal which were supported by some typical examples. In this review paper, we report additional examples of explosives scattered over in the literature to validate the ‘Salt Formation’ & ‘Introduction of Amino Group/s’ approaches for imparting/improving the thermal stability of explosives. Wherever data is not available in the literature, the same has been calculated using Energetic Materials Designing Bench (EMDB), Version 1.0. The data generated on a large number of explosives bring out validation of ‘Salt Formation’ & ‘Introduction of Amino Group/s’ approaches for imparting/improving the thermal stability of explosives. Further, as the number of amino group/s increases, thermal stability also increases. In addition, density, impact sensitivity & velocity of detonation data of these explosives which are also essential from their application point of view, have been reported. This study also reveals that explosives TAHNDPA, TADTNPEDA, TADTNPATNB & KTAHNDPA (Table 2) appear to be potentially better thermally stable explosives than TATB, a benchmark thermally stable explosive at present.
