TL;DR: In this paper, a method for preparing superfine spherical TEX crystal is described, which comprises the following steps of: firstly, adding TEX into dimethyl sulfoxide at a temperature of between 80-100 DEG C, and stirring until the TEX is completely dissolved to prepare a saturated solution; then, mixing tetrabutylammonium bromide and water under an ice bath condition to obtain a mixed solution; and finally, slowly dropping TEX saturated solution into the mixed solution according to a volume ratio of the dimethyl sulphoxide to the water
Abstract: The invention discloses a method for preparing superfine spherical TEX crystal. The method comprises the following steps of: firstly, adding TEX into dimethyl sulfoxide at a temperature of between 80-100 DEG C, and stirring until the TEX is completely dissolved to prepare a saturated solution; then, mixing tetrabutylammonium bromide and water under an ice bath condition to obtain a mixed solution;and finally, slowly dropping the TEX saturated solution into the mixed solution according to a volume ratio of the dimethyl sulfoxide to the water of 1:15-30 to prepare the superfine TEX powder. Theprepared superfine spherical TEX explosive crystal product has the advantages of near-spherical shape, few edges and corners, smooth surface, obviously improved thermal stability and reduced mechanical sensitivity. According to the invention, TEX crystals with different particle sizes can be prepared by changing process conditions, and the TEX crystals can be used as an energy-containing passivator to provide raw material support for particle grading of mixed explosive.
TL;DR: In this article, the thermal decomposition behaviors of 4,10-dinitro-2,6,8,12-tetraoxa-4,10diazaisowutrzitane (TEX) were studied by using accelerating rate calorimetry to achieve the hazard assessment of TEX explosive, and the kinetic parameters were studied from the measured self-heating rate data by assuming a zero-order reaction.
Abstract: The thermal decomposition behaviors of 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazaisowutrzitane (TEX) were studied by using accelerating rate calorimetry to achieve the hazard assessment of TEX explosive, and the kinetic parameters were studied from the measured self-heating rate data by assuming a zero-order reaction. Moreover, the specific heat capacity date of TEX was obtained from differential scanning calorimetry. These results could be contributed to improve the safety in the reaction, transportation, and storage processes of TEX.
