【 摘 要 】

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: d�? / dt =10^22.01 (1-�? )[-ln(1-�? )]^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 ( ツS ^× ), enthalpy of activation (ツH ^×), and Gibbs free energy of activation ( ツG^×) 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.
