Preparation, Characterization and Non-isothermal Kinetics of the Dehydration Process of [Sm（p-MOBA）3bath]2·4H2O

The new complex of [Sm(p-MOBA)3bath]2·4H2O (p-MOBA, p-methoxybenzoate; bath, 4,7-diphenyl-1,10-phenanthroline) was synthesized and characterized by elemental analysis, molar conductance, IR, UV and XRD patterns. The thermal decomposition of the complex was studied under the non-isothermal condition by TG-DTG and IR techniques. The most probable mechanism function of the dehydration process was obtained from the analysis of DSC curves of the complex employing the double extrapolated method on the basis of integral isoconversional non-linear (NL-INT) and Tang-Wanjun integral equations. The integral function of the mechanism was [1− (1−α)1/2]1/2 and the corresponding kinetic parameters (activation energy E and the pre-exponential factor A) were obtained.
