The thermal decomposition of [Eu 2( p MOBA) 6(phen) 2](H 2O) 2 ( p MOBA=C 8H 7O 3, methoxybenzoate; phen=C 12 H 8N 2, 1,10 phenanthroline) and its kinetics were studied under the non isothermal condition in air by TG and DTG methods. The intermediate and residue for each decomposition were identified from TG curve. The non isothermal kinetic data were analyzed by the Achar method and Coats Redfern method. The possible reaction mechanisms were suggested by comparing the kinetic parameters. The kinetic equation for the first stage can be expressed as d α /d t = A exp(- E/RT )[-ln(1- α )] -1 , the second stage and the third stage d α /d t = A exp(- E/RT )3/2(1- α ) 4/3 [1/(1- α ) 1/3 -1] -1 . The mathematical expressions of the kinetic compensation effects of each stage of the thermal decomposition reaction were also obtained.

The intermediate and residue for each decomposition were identified from TG curve. The non isothermal kinetic data were analyzed by the Achar method and Coats Redfern method. The possible reaction mechanisms were suggested by the kinetic equation for the first stage can be expressed as d α / dt = A exp (- E / RT) [- ln (1- α)] -1, the second stage and the third stage d α / dt = A exp (- E / RT) 3/2 (1- α) 4/3 [1 / (1- α) 1/3 -1] -1.
