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 。
TG DTG and DTA techniques were used to study the non-isothermal thermal decomposition process and kinetics of 2,2 ’-bipyridyl-p-methoxybenzoate (Europium (Ⅲ)) in static air. The TG The kinetic equation of the first step is deduced as: dα / dt = Aexp (E / RT) 2 (1 α) 1/2 by using the differential method and the integral method to analyze the non-isothermal kinetic data.
