Properties of TATB

It is a yellow-brown coloured substance which decomposes rapidly just below its melting temperature. It has excellent thermal stability in the range 260-290 °C and is known as a heat-resistant explosive. Some of the properties of TATB are given in Table 2.17.

Al,A -Bis(l,2,4-triazol-3-yl)-4,4 -diamino-2,2, 3,3, 5,5, 6,6 -octanitroazobenzene (BTDAONAB) (105) has recently been synthesized by Agrawal and co-workers by tandem nitration-oxidative coupling of 4-chloro-3,5-dinitroaniline (103) followed by displacement of the chloro groups with 3-amino-1,2,4-triazole. This is a thermally stable explosive with some impressive properties, exceeding TATB in both thermal stability and explosive performance (VOD 8321 m/s, d = 1.97 g/cm ). This compound doesn t melt and the DTA exotherm is not seen until 550 °C.

A number of explosives for various applications have been synthesized, characterized for structural aspects, thermal and explosive properties by us in India and are being evaluated [193-198] for their intended end-use. The evaluation of BTATNB [Structure (2.27)] indicates that it is slightly more thermally stable than PATO [Structure (2.24)] coupled with better insensitivity toward impact and friction [71]. The data on thermal and explosive properties of some aromatic nitrate esters suggest that l,3,5-tris(2-nitroxyethyl nitramino)-2,4,6-trinitrobenzene [Structure (2.54)] is a potential substitute of PETN [193]. An explosive called 2,4,6-tris (3,5 -diamino-2, 4, 6 -trinitrophenylamino)-l,3,5-triazene [designated as PL-1 Structure (2.55)] is a new thermally stable and insensitive explosive which on comparison with TATB suggests that it is slightly inferior to TATB [Structure...

Methyl-2,4,5-trinitroimidazole has been synthesized from 4-nitroimidazole using stepwise nitration and further methylation by dimethylsulfate or from commercially available imidazole. l-Methyl-2,4,5-trinitroimidazole is relatively insensitive to impact, and its thermal stability is excellent. The calculated detonation properties point to the fact that its performance is about 30% better than that of TATB. The data of impact sensitivity, friction sensitivity, time-to-explosion tern-... 

Results of analyzing Gibbs energy of transfer data on the basis of equation (4.9.8) for five alkali metal halides and TATB from water to various non-aqueous solvents are summarized in table 4.11. Acceptable fits to equation (4.9.6) are obtained for these systems, the correlation coefficient r decreasing with increase in the size of the alkali metal cation and halide anion. However, there is a problem in assessing the properties of the fit on the basis of the response factors and p. ...
