Thermochemical properties and non-isothermal decomposition reaction kinetics of 3,4-dinitrofurazanfuroxan (DNTF)

Abstract: The constant-volume combustion energy, (DNTF, s, 298.15K) and kinetic behavior of the exothermic decomposition reaction of the title compound (DNTF) are determined by a precise rotating bomb calorimeter and DSC, respectively. Its standard enthalpy of combustion, (DNTF, s, 298.15K), standard enthalpy of formation, (DNTF, s, 298.15K) and kinetic parameters of the major exothermic decomposition reaction in a temperature-programmed mode [the apparent activation energy (Ea) and pre-exponential factor (A)] are calculated. The values of (DNTF, s, 298.15K), (DNTF, s, 298.15K), and (DNTF, s, 298.15K) of DNTF are -9733.96 ± 8.59Jg-1, -3018.29 ± 2.68kJmol-1, and 657.23 ± 2.70kJmol-1, respectively. The kinetic model function in integral form and the value of Ea and A of the major exothermic decomposition reaction of DNTF are , 177.03kJmol-1 and 1013.68s-1, respectively. The critical temperature of thermal explosion of DNTF is 240.6°C. [Copyright &y& Elsevier]
