Abstract

The insensitive explosive 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) has been recrystallized from dimethylsulfoxide (DMSO) with particle sizes ranging up to 2 mm diameter. Crystal growth was controlled by varying the heating and cooling rates and the solution agitation speed. The role of additives and “green” u.v. radiation-induced impurity in affecting crystal morphology, size, and colour was also studied. To provide the thermal concentration data needed for the crystallization study, the solubility curve of TATB in DMSO was determined gravimetrically. The solubility data spans the range of 0.47±0.23 gl−1 at 21.2 °C to 6.80±1.13 gl−1 at 145.5 °C.
