Abstract
4-Amino-1,2,4-triazole copper complex (4-ATzCu) was synthesized, and its thermal behaviors, nonisothermal decomposition reaction kinetics were studied by DSC and TG-DTG techniques. The thermal decomposition reaction kinetic equation was obtained as: dα / dt =1022.01 (1-α )[-ln(1-α )]1/3 exp(-2.75×104 /T) . The standard mole specific heat capacity of the complex was determined and the standard molar heat capacity is 305.66 J·mol-1·K-1 at 298.15 K. The entropy of activation ( ΔS ), enthalpy of activation (ΔH ), and Gibbs free energy of activation ( ΔG) are calculated as 171.88 J·mol-1·K-1, 225.81 kJ·mol-1 and 141.18 kJ·mol-1, and the adiabatic time-to-explosion of the complex was obtained as 389.20 s.
