N2 - To study the stability of 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.05,903,11]-dodecane (TEX), a high performance liquid chromatography (HPLC) analysis method for TEX was developed. The thermal behavior of TEX was studied by thermogravimetry-derivative thermogravimetry (TG-DTG) and differential scanning calorimetry (DSC), the peak temperatures at different heating rates (5,10,15,20 and 25 K/min) were determined. The apparent activation energy (Ek) and preexponential constant(A) of the exothermic decomposition reaction were calculated by Kissinger's method. Activation enthalpy (△S≠), activation entropy (△H≠) and activation Gibbs free energy (△G≠) for the exothermic decomposition reaction of TEX were calculated according to thermodynamic equations. The results indicate that TEX is stable to heat. The values of △S≠, △H≠ and △G≠ are 501.03 J/(K·mol), 432.48 kJ/mol and 145.26 kJ/mol, respectively.
