Abstract  

A method for estimating the critical temperatures (Tb) of thermal explosion for energetic materials is derived from Semenov’s thermal explosion theory and the non-isothermal kinetic equation dα/dt=A0TBf(α)e−E/RT using reasonable hypotheses. The final formula of calculating the value of Tb is

(Tb−Te0=1. The data needed for the method, E and Te0, can be obtained from analyses of the non-isothermal DSC curves. When B=0.5 the critical temperature (Tb) of thermal explosion of azido-acetic-acid-2-(2-azido-acetoxy)-ethylester (EGBAA) is determined as 475.65 K.
