The thermal behavior of N, N’-bis (3-aminopropyl) oxalamide and triethanolamine complexes in a dynamic air atmosphere was investigated by TG-DTG-DTA thermometry. Differential thermal analysis (Achar method) (Coats-Redfen method) was used to cope with non-isothermal TG data. By comparing the kinetic parameters E and ln A of thermal decomposition, the thermal decomposition kinetic equation of the first phase of the complex was proposed: dα / dt = Ae-E / -α) 2 and the second-stage thermal decomposition kinetic equation: dα / dt = Ae-E / RT (1-α); and the mathematical expressions of E and ln A
