摘要
采用TG DTG和DTA技术研究了2,2' 联吡啶 对甲氧基苯甲酸铕(Ⅲ)在静态空气中的非等温热分解过程及动力学 ,根据TG曲线确定了热分解过程中的中间产物及最终产物 ,运用微分法与积分法对非等温动力学数据进行分析 ,推断出第一步的动力学方程为dα/dt=Aexp( E/RT)2(1 α)1/2 。
The thermal decomposition of the 2,2' dipyridine tris(p methoxybenzoats) europium(Ⅲ) and its kinetics were studied under the non isothermal condition in air by TG DTG and DTA methods. The intermediate and residue for each decomposition were identified from TG curve. The non isothermal kinetic data were analyzed by means of integral and differential methods. The possible reaction mechanisms were investigated by comparing the kinetic parameters. The kinetic equation for the first stage can be expressed as dα/dt=Aexp( E/RT)2(1 α)1/2。
