✦ Synopsis

The products of sublimation and thermal decomposition of 1,3,5-triamino-2,4,6-trinitmbenzene have been determined mass spectrometrically in the temperature range 200-300°C employing both the effusion and Langmuir evaporation methods. Electron impact ionization energies 1-2 eV above appearance potentials were employed to eliminate fragmentation of larger species. The unusual crystal structure of TATB results in long C-C bonds, with considerable hydrogen bonding. At 250°(2 the molecule sublimed readily, with some thermal decomposition, causing the splitting of the molecule into two fragments at amu 144 and 114. Further fragmentation of these species to lower ainu molecules occured. The effusion experiments produced numerous low molecular weight species, indicating that the initial radicals were relatively shortlived.
