摘 要: | 在乙醇-水混合体系中合成了1,10-菲啰啉(phen)的三种稀土配合物Nd(phen)(CH3COO)2(NO3)(1),Eu(phen)2(NO3)3(2),Ho(phen)2(NO3)3(3).采用TG-DTG和DTA技术研究了配合物在静态氮气中的热分解过程,并用Achar法和Coats-Redfern法对各配合物的非等温热力学数据进行了分析,推断出各反应的热分解反应机理及热分解反应动力学方程式,计算出了其表观活化能(E)和指前因子的对数值(lnA).

Abstract: | Three lanthanide complexes Nd(phen)(CH3COO)2(NO3)(1),Eu(phen)2(NO3)3(2)and Ho(phen)2(NO3)3(3)were synthesized with 1,10-phenoline(phen)as ligand in the system of EtOH /H2O.The thermal decompositions of the complexes were studied in static nitrogen by TG-DTG and DTA methods.The non-isothermal kinetic data of the complexes were analyzed by using the Achar and Coats-Redefern methods,then the possible reaction mechanisms of the thermal decompositions and kinetic equation were suggested,and values of activation energies(E)and pre-exponential factors(lnA)were given respectively. |
