利用TG-DTG及DSC技术研究了Nd(C5H8NO3)2(C3H5N2)2C l3.4H2O在氮气中的热分解过程;采用Achar微分法和Coats-Redfern积分法对配合物进行动力学分析,推断出脱水阶段的热分解反应的可能机理,求出该配合物热分解的非等温动力学数据,结果显示,脱水过程属于n=1/2的成核生长机理,其动力学方程为dα/dt=Aexp(-E/RT){(1-α)[-ln(1-α)]-1/2}.
The thermal decomposition process of Nd (C5H8NO3) 2 (C3H5N2) 2C13.4H2O in nitrogen was studied by TG-DTG and DSC techniques. The kinetics of the complex was also investigated by Achar differential method and Coats-Redfern integral method, The results show that the dehydration process belongs to the nucleation and growth mechanism of n = 1/2, and the kinetic equation is: dα / dt = Aexp (-E / RT) {(1-α) [- ln (1-α)] - 1/2}.
