  Isothermal decomposition kinetic of three lanthanide mixed complexes with the general formula of Ln(thd)3phen (where Ln=Nd3+, Sm3+ or Er3+, thd=2,2,6,6-tetramethyl-3,5-heptanodione and phen=1,10-phenanthroline) has been studied in this work. The powders were characterized by their melting point, elemental analysis, FTIR spectroscopy and thermogravimetry. The isothermal TG curves have been recorded under the same conditions at 265–285, 265–285 and 250–270°C for Nd(thd)3phen, Sm(thd)3phen and Er(thd)3phen, respectively. The kinetic parameters, i.e. activation energy, reaction order and frequency factor were obtained through the technique of lineal regression using the relation g(α)=kt+g 0. The analysis was done at decomposed fractions between 0.10–0.90. The values of activation energy were: 114.10, 114.24 and 115.04 kJ mol–1 for the Nd(thd)3phen, Sm(thd)3phen and Er(thd)3phen complexes, respectively. The kinetic models that best described the isothermal decomposition reaction the complexes were R1 and R2. The values of activation energy suggests the following decreasing order of stability: Nd(thd)3phen

  本研究中对三种具有一般公式Ln(thd)3phen的镧系混合络合物的等温分解动力学进行了研究（其中Ln=Nd3+、Sm3+或Er3+，thd=2,2,6,6-四甲基-3,5-庚二酮，phen=1,10-菲咯啉）。采用熔点、元素分析、FTIR光谱和热重法对粉末进行了表征。在265–285°C、265–285°C和250–270°C的相同条件下，分别记录了Nd(thd)3phen、Sm(thd)3phen和Er(thd)3phen的等温TG曲线。通过线性回归技术利用关系g(α)=kt+g 0获得了动力学参数，即活化能、反应级数和频率因子。分析是在0.10–0.90的分解分数范围内进行的。活化能的值分别为：Nd(thd)3phen、Sm(thd)3phen和Er(thd)3phen络合物的活化能为114.10、114.24和115.04 kJ mol–1。最佳描述该络合物等温分解反应的动力学模型是R1和R2。活化能的值表明其稳定性呈现如下递减顺序：Nd(thd)3phen。
