【Abstract】 The mechanism of thermal decomposition of terbium complexes with benzene carboxylic acid has been studies by TG-DTG-DTA. The intermediates were characterized by infrared spectra, elemental analysis, and chemical analysis. The activation energies for dehydration and decomposition reaction of complexes have been calculated by Kissinger, Ozawa, and simulated kinetic method, and the results calculated were compared for same process. The enthalpy changes for dehydration and phase change reaction were determined.更多还原
