合成了对甲基苯磺酰化丝氨酸配体(L)和对甲基苯磺酰化丝氨酸Nd(Ⅲ)配合物。通过元素分析、热分析、红外光谱、紫外光谱和摩尔电导等分析技术,确定配合物的组成为NdL3。用非等温热重分析方法研究了Nd(Ⅲ)配合物的热分解反应动力学,分解反应一步进行,其分解的动力学方程为dα/dt=Aexp(-Ea/RT)(1-α)2,并计算出了该步热分解的活化熵ΔS#、活化吉布斯自由能ΔG#和活化焓ΔH#分别为-86.7674J/mol.K、219.3884kJ/mol、170.9938kJ/mol。
The p-methylbenzenesulfonated serine ligand (L) and the p-methylbenzenesulfonated serine Nd (Ⅲ) complex were synthesized. The composition of the complex was determined to be NdL3 by elemental analysis, thermal analysis, infrared spectroscopy, UV spectroscopy and molar conductivity analysis. The kinetics of the thermal decomposition of Nd (Ⅲ) complexes was studied by non-isothermal thermogravimetric analysis. The decomposition kinetics was as follows: dα / dt = Aexp (-Ea / RT) ) 2, and the activation entropy ΔS # of thermal decomposition at this step was calculated. The Gibbs free energy ΔG # and activation enthalpy ΔH # were -86.7674 J / mol.K, 219.3884 kJ / mol and 170.9938 kJ / mol, respectively.
