摘要
用非等温热重法研究了Ni(CH3COO)2·4H2O脱水反应的动力学方程和动力学参数,实验数据以Achar法、Coats-Redfern法、MKN法处理得到脱水反应的动力学方程为dα/dt=Aexp(-E/RT)(1-α),活化能为E=91.30kJ/mol,指前因子lg(A/S-1)=10 37,对反应的动力学补偿效应方程进行了研究.
The dehydration kinetic equation and the kinetic parameters of Ni(CH_3COO)_2·4H_2O were studied under non-isothermal condition. The data were treated by Achar method, Coats-Tedfern method and MKN method. It shows that the kinetic equation of the dehydration is dα/dt=Aexp(-E/RT)(1-α), activation energy E is 91.30 kj/mol, pre-exponential factor lg(A/S^(-1))=10.37. The kinetic compensation effect equation has also been studied.
