摘要：

The thermal decomposition of Eu-2 (omicron-MBA)(6) (PHEN)(2) (omicron-MBA = CH3C6H4COO, methylbenzoate; PHEN = C12H8N2, 1, 10-phenanthroline) and its kinetics were studied by thermogravimetry-differential thermogravimetric (TG-DTG) method. The intermediate and residue for each step of decomposition were identified from TG curve. The mechanism function and kinetic parameters were obtained from the analysis of TG-DTG curve by the Achar method, the Madhusudanan-Krishnan-Ninan (MKN) method and the Ozawa method. The lifetime equation it weight-loss of 10% was deduced as lntau = 24.3690 + 1.5284 x 10(4)/T by isothermal thermogravimetric analysis.
