| Abstract: In this paper,three kinds of Schiff base complexes with Cu(Ⅱ) which derived from o-vanillin were synthesized. The thermoanalysis of the complexes were studied. Kinetic parameters were obtained from analysis of TG, DTG curves by integral and differential methods;The possible reaction mechanisms were suggested by comparison of the kinetic parameters.The kinetic equations may be expressed as: cpl, da / dt= A·e-E/RT·3(1-a)2/3;cp2, da / dt= A·e-E/RT·(1-a)2;cp3, da / dt= A·C-E/RT· 1 |
| Keywords: Schiff base copper(Ⅱ) complex kinetics of thermal decomposition |
