摘要
Abstract
The thermal decomposition characteristics of DNTF and 2 ,4 ,6‐trinitrotoluene (TNT) were investigated by means of differential scanning calorimetry at different heating rates .The kinetic parameters of thermal decomposition reaction ,critical tem‐perature of thermal explosion and thermodynamic parameters were calculated ,contrasted and analyzed by Kissinger methed .The results show that the thermal decomposition process of DNTF is different with TNT ,it occurs in two stages and the first acts as the major part .The activation energy of DNTF is 168 .85kJ/mol ,which is about 58kJ/mol higher than that of TNT ,revealing that DNTF has a good thermal stability at low temperature .However ,all the other thermodynamic parameters of DNTF are higher than those of TNT except the free energy of activation .The decomposition peak temperatures and critical temperature of thermal explosion of DNTF are lower than those of TNT .So ,the thermal stability of DNTF is poorer than that of TNT .关键词
