THE EXPLOSIVE PROPERTIES OF THE AMINO-SUBSTITUTED, SYMMETRICAL TRINITROBENEZENES
Abstract
The shock sensitivity and failure diameters of four explosive compounds of the trinitrobenzene series: 1, 3, 5-trinitrobenzene (TNB), 1-amino 2,4,6-trinitrobenzene (TNA), 1,3-diamino 2,4,6 trinitrobenzene (DATB) and 1,3,5- triamino 2,4,6-trinitrobenzene (TATB) are functions of the number of amino groups, heats of formation and oxygen balance. The most sensitive, TNB, has the lowest heat of formation and oxygen balance. Detonation failure occurs at diameters of < 0.3 cm TNB, 0.3 cm TNA, 0.53 cm DATB and 1.3 cm TATB. The detonation velocity-charge density relation, D(m/sec) 2480 2852 mo(g/cc), and the measured detonation energies of 815 = 15 cal/g are the same for each series member. The measured detona tion pressures are 259.4 kb and 174.6 kb for TATB at densities of 1.80 g/cc and 1.50 g/cc, 251.0 kb for DATB at 1.80 g/cc, and 219.2 kb for TNB at 1.64g/cc. Rapidly applied shocks, with peak pressures as high as 100 kilobars in the NOL wedge test, fail to detonate 12.7 mm thick TATB samples. On the other hand, under such shock con ditions, the other three compounds are at least as sensitive as Composition B. Each, however, is less sensitive than pressed TNT to slowly applied pressure pulses such as might develop in an impact accident. (Author)
