Synthesis, characterization, and thermal decomposition kinetics of deuterated 1,3,5-triamino-2,4,6-trinitrobenzene

TATB and TATB-d6 were synthesized using phloroglucinol as raw material. Their molecular structure and micromorphology of them were well characterized by FTIR, NMR spectroscopy, XRD and FE-SEM. The thermal behaviors of these compounds were studied with TG-DSC, and the non-isothermal kinetic decomposition parameters of the two compounds were gained using the method of Friedman (FM). The apparent activation energy value of TATB-d6 was larger than that of TATB, which indicated the heat stabilization of deuterated TATB particles was improved. Finally, the thermal detonation critical temperatures of these two products were also calculated and discussed.
