The thermal decomposition of the complex of Cu(II) with N-(2-hydroxyethyl)salicyldimino and its kinetics were studied under the non-isothermal condition by TG and DTG techniques. The non-isothermal kinetic data were analyzed by means of Achar method and Coats-Redfern method. The possible reaction mechanism was suggested by comparing the kinetic parameters. The results show that this thermal decomposition is three-dimension diffusion, 3D(cylinder symmetry). The kinetic equation can be expressed as: da/dt = A譭-E/RT?/2[(1-a)-1/3-1]-1.
