【Abstract】 The thermal decomposition kinetics of title complex was investigated under non- isothermal condition. TG and DTG curve, indicate that the complex decomposed in four steps: Kinetic parameters were obtained from analysis of TG, DTG curves by integral and differential methods. The possible reaction mechanism was suggested by comparison of the kinetic parameters. The mathematical expression of the kinetic compensation effect is found. The kinetic equation and compensation effect of step(1), (3) and (4) can be expressed respectively as follows: (1)dα/dt = (A/)e- E/RT,(3/2) (1 -α)4/3[ (1 -α)-1/3 -1] -1,ln A = 0. 340 0 E - 6. 892; (3)dα/dt = (A/ )e-E/RT(3/2) [(1- α)-1/3 -1]-1,ln A = 0. 184 5 E -6. 356; (4)dα/dt = (A/)e- E/RT(3/2) (l -α) [-ln(1 -α)]1/3,lnA = 0. 164 2 E -6. 755.更多还原
