“…The TATB-based explosive, LX-17, decomposed more slowly, with lifetimes ranging from 20±25 s. The slow-burning nature of TATB has been observed in previous studies not involving molten salts (12±14) . There may be chemical kinetic reasons for slow reaction rates, as discussed by Glazkova and Kazarova (13) . They found that the interaction of nitro groups and amino groups results in the formation of an intermediate cyclic complex.…”

“…For HMX, it is known that abstraction of an H atom will initiate decomposition (18,32) . In addition, since H atoms are thought to be involved in the formation of the inhibiting intermediate complex in TATB (13) , it is reasonable to assume that abstraction of H atoms from TATB may result in increased reaction rates with this material as well. The possibility that the salts abstract H atoms from HMX and TATB will be considered here.…”

Hochgeschwindigkeitsbildanalyse der Zersetzu È ng von auf TATB und HMX basierenden energetischen Materialien in geschmolzenen SalzenUntersucht wird die Einbringung energetischer Materialien in Hochtemperaturba Èder geschmolzener Salze als eine Methode zu ihrer sicheren Vernichtung. In diesen Ba Èdern zersetzt sich das Material. In der vorgestellten Forschungsarbeit wird das Verhalten der Sprengstoffe LX-17 (92,5 Gew.% 1,3,5-Triamino-2,4,6-trinitrobenzol (TATB), 7,5 Gew.% Kel-F Kunststoffbinder) und 3,5,3,5, SummaryImmersion of energetic materials into high-temperature molten-salt baths, where the energetic materials decompose, is being considered as a method for their safe destruction. In the present research, behaviors of the high explosives LX-17 (92.5 wt% 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), 7.5 wt% KeI-F 800 plastic binder) and 3,5,3,5,, 15 wt% Viton A plastic hbinder) were studied when these materials were immersed into molten salt baths. Pressed cylindrical samples initially 6.35 mm in diameter and length were immersed in molten salt baths, and data were taken photographically. Sample decomposition behaviors were observed for varied salt temperatures in a molten LiClNaCl-KC1 eutectic and then separately in a molten Li 2 CO 3 -Na 2 CO 3 -K 2 CO 3 eutectic. Bath temperatures ranged from 650 to 750 C. General combustion behaviors such as bubble formation characteristics, gas evolution, and sample lifetimes were observed. Results indicated that sample lifetimes decreased as bath temperatures increased, and that the carbonate eutectic increased initial decomposition rates and decreased sample lifetimes relative to the chloride eutectic.
