摘要：
Thermal depyridination mechanism and the non-isothermal kinetics of (mu-2-nitrobenzoato-kappa O-2:O':O')bis-[(pyriden-kappa N) zinc(II)] was studied by TG method. The decomposition residue of this complex was characterized by XRD. The data from non-isothermal experiments were analyzed by Achar and the improved methods. It was found that the depyridination process is. governed by three-dimensional diffusion (spherical symmetry, 2D3) and the kinetic equation is 3/2(i-alpha)(2/3)[1-(1-alpha)(1/3)](-1).
