Abstract:

: The thermal behavior and thermal decomposition kinetic parameters of ethane-1,2-diamine copper (II) chloride (EDCC) in a temperature-programmed mode have been investigated by mean of TG-DTG. There are four stages in the thermal decomposition process. The kinetic parameters of the apparent activation energy Ea (130.2, 143.6 and 158.9 KJ·mol–1) and per-exponential factor A (1011.80, 1012.18 and 1011.83 s–1) in II, III and IV stages were obtained from analysis of the TG-DTG curves by Kissinger method. The values of Ea indicated that the difficulty coefficient of pyrolysis in II, III and IV stages was increased in the order: II < III < IV. The values of the entropy of activation ΔS≠, enthalpy of activation ΔH≠ and free energy of activation ΔG≠ of the reaction were estimated.
