0 IntroductionThe complexes formed by rare earth and aromatic carboxylic acid have many special structuresand interesting luminous properties, thus arouse people's interest to study them. They can be used.in many areas such as extraction and separation, germicide, catalyst, luminous materials andfunctional materials and so on.The crystal structure and luminescence spectra of the europium p-chlorobenzoate complex withl, 10-phenanthroline has been reported"], but the study for its non-isothermal…

Thermal Decomposition Mechanism and Non-isothermal Kinetics of the Complex Eu_2(p-ClC_6H_4COO)_6(C_(12)H_8N_2)_2

The thermal decomposition behaviour of europium p-chlorobenzoate complex with l, 10-phenanthroline and its kinetics were studied in nitrogen by non-isothermal thermogravimetry. Its thermal decomposition occurs mainly in three steps.. The intermediate and residue for each step of decomposition were identified from TG curve. The kinetic parameters were obtained from analysis of the TG-DTG curves by the Achar method. the Madhusudanan- Krishnan-Niman (MKN ) method and Ozawa method respectively. The most probable mechanisms function for the first and second stage were suggested by comparing the kinetic parameters.
