“…The Differential Scanning Calorimetry (DSC) thermogram [23] in Fig. 7 shows that TATB exothermic decomposing temperature lies between 360 and 390 • C indicating its excellent thermal stability and heat resistance.…”

“…39 Recently in an attempt to make fine TATB particles superacids methane and ethane sulfonic acid and hexamethylphosportriamide were found to dissolve TATB. 40 Sulfolane was selected because of its relatively rapid dissolution of TATB at 190ºC and sharp and rapid precipitation characteristics on lowering the temperature to 175ºC.…”

Two newly synthesized versions of the insensitive high explosive (IHE) 1,3,5-triamino-2,4,6-trinitrobenzenes (TATBs) were compared to two legacy explosives currently used by the Department of Energy. Except for thermal analysis, small scale safety tests could not distinguish between the different synthetic routes.Morphologies of new TATBs were less faceted and more spherical. The particle size distribution of one new material was similar to legacy TATBs, but the other was very fine. Densities and submicron structure of the new TATBs were also significantly different from the legacy explosives. Pressed pellets of the new explosives were less dense. Recrystallization from sulfolane improved the density and thermal stability of both new TATBs, though the morphology of the recrystallized TATB was nearly hexagonal platelets.

“…Walter Selig [21] studied in detail the solubility of TATB in various solvents. The insolubility of TATB causes difficulty in sample preparation for analytical techniques [22,23]. Its insolubility is related to the strong intra-and inter-molecular hydrogen bonds (between the nitro and amino groups) present in the molecular packing of the crystal lattice [24].…”

Abstract:The main hurdle for the estimation of the purity of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) is its insolubility in most of the known organic solvents. In the conventional method, TATB is digested with steam in a modified Kjeldahl digester and the ammonia evolved is estimated quantitatively. To do away with this cumbersome method, a simple, rapid HPLC technique using a reverse phase C-18 column has been established for quantitative determination of the purity of TATB. A sharp and symmetrical peak with a retention time of 2.92 min at 355 nm is obtained for pure TATB when the flow rate is 2.0 mL/min. The linearity of the detector response has been studied with sample concentrations ranging from 10 to 50 mg/L. The method addresses two important issues of sample preparation and the precision of measurement. Unlike the previously reported HPLC techniques which mainly aimed at the detection of TATB, the present work is a validated account of a quantitative estimation of purity. Regular production batch samples have been assayed by this method and the results are compared with those obtained from the conventional analysis. The HPLC method is convenient and reliable for quality control of the product at the plant level.
