Abstract
AbstractThe constant‐volume combustion energy, ΔcU (GUDN, s, 298.15 K), enthalpy of solution in acetic ether, Δ Hθm and kinetic behavior of the exothermic decomposition reaction of the title compound (GUDN) are determined by a precise rotating bomb calorimeter, a Calvet microcalorimeter and DSC, respectively. Its standard enthalpy of combustion, Δ, Hθm: (GUDN, s, 298.15 K), standard enthalpy of formation, Δ, Hθm (GUDN, s, 298.15 K) and kinetic parameters of the exothermic main decomposition reaction in a temperature‐programmed mode [the apparent activation energy ( Ea ) and pre‐exponential factor (A)] are calculated. The values of ΔcU (GUDN, s, 298.15 K), Δ Hθm (GUDN, s, 298.15 K), Δ, Hθm (GUDN, s, 298.15 K) and Δsol Hθm of GUDN are (‐7068.64×2.37) I‐g (‐1467.66×0.50) kJ · mol−1, (‐319.76×0.58) kJ · mol−1 and (165.737×0.013) kJ·mol−1, respectively. The kinetic model function in integral form and the value of Ea and A of the exothermic main decomposition reaction of GUDN are 220.20 kl · mol−1 and 1021.18 s−1, respectively. The critical temperature of thermal explosion of GUDN is 217.6 °C.
