| Abstract: | Three mononuclear complexes were synthesized and characterized by elemental analyses, molar conductivity and IR spectral studies. A kinetic study of the thermal decomposition reactions of copper( Ⅱ ) complexes with N, N' - bis(alkylaminoalkyl) oxamide was carried out using TG and DTA technique under dynamic air atmosphere. The non- isothermal kinetics data were analyzed by means of the Achar method and the Coats - Redfen method. The most probable kinetic model was suggested by comparison of the kinetic parameters. The activation energies, entropies, and the pre-exponential factor of the thermal decomposition reactions were calculated with thermogravimetric curves. The initial temperature of decomposition was compared with those obtained for the complexes N, N'-bis(2-aminopropyl)oxamidocopper( Ⅱ ), N, N'-bis(2-aminopropyl) oxamidoc-opper( Ⅱ ), and N, N'-bis(3-aminopropyl)oxamidoeopper( Ⅱ ). The sequence of thermal stability is: Cu( oxpn) ＞ Cu(oxap) ＞ Cu(oxen). |
