| 摘 要： | The complex [Sm（p-MBA）3phen]2 （p-MBA, p-methylbenzoate; phen, 1,10-phenanthroline） was prepared and characterized by elemental analysis, IR and UV spectra. The thermal decomposition process of [Sm（pMBA）3phen]2 was studied under a static air atmosphere by TG-DTG and IR techniques. Thermal decomposition kinetics was investigated employing a newly proposed method, together with the integral isoconversional non-finear method. Meanwhile, the thermodynamic parameters （AH#, △G# and AS#） were also calculated. The lifetime equation at mass-loss of 10% was deduced as In r=-24.7825＋ 18070.43/T by isothermal thermogravimetric analysis.

| Abstract: | The complex [Sm(p‐MBA)3phen]2 (p‐MBA, p‐methylbenzoate; phen, 1,10‐phenanthroline) was prepared and characterized by elemental analysis, IR and UV spectra. The thermal decomposition process of [Sm(p‐ MBA)3phen]2 was studied under a static air atmosphere by TG‐DTG and IR techniques. Thermal decomposition kinetics was investigated employing a newly proposed method, together with the integral isoconversional non‐linear method. Meanwhile, the thermodynamic parameters (ΔH≠, ΔG≠ and ΔS≠) were also calculated. The lifetime equation at mass‐loss of 10% was deduced as ln τ=?24.7825+18070.43/T by isothermal thermogravimetric analysis. |
