The enthalpies of the crystal transformation from I to II and from II to III and the melting enthalpy of 2,2,2-trinitroethyl-4,4,4-trinitrobutyrate (TNETB) are determined by means of Calvet microcalorimeter. On cooling, the supercooing from liquid to solid does not appear, and form II will transform to form I when 71.8° C is reached. The phase diagrams of TNETB-2,4,6-trinitrotoluene (TNT) and TNETB-polyester systems have been constructed by differential scanning calorimetry (DSC). The eutectic temperatures are 56° C and 34° C respectively. The compositions corresponding to the eutectic points are 52 and 46 weight percent TNETB respectively. 相似文献

A numerical method of computing the kinetic parameters (the activation energy (E), the preexponential constant (A) and the reaction order (n)) of exothermic decomposition of energetic materials via the exothermic rate equation is presented. The values ofE, A, andn are reported for the exothermic decomposition of six typical energetic materials, 1,6-diazido-2,5-dinitrazahexane (I), 1,5-diazido-3-nitrazapentane (II), 2,2,4,7,9,9-hexanitro-5-methyl-4,7-dinitrazadecane (III), 2,2,2-trinitroethyl-4,4,4-trinitrobutyrate (IV), 1,4-dinitro-2,3-dioxo-1,4-dinitrazacyclohexane (V) and 1,3,5-trianitro-1,3,5-triazafurazano[3,4-f]cycloheptane (VI).
