Popescu法研究一水合乙酸铜的热分解动力学

Study on Thermal Decomposition Kinetics of Copper Acetate Dihydrate with Popescu Method

用TG-DTG技术研究了一水合乙酸铜在静态空气中的热分解过程,根据TG曲线确定了热分解过程中的中间产物及最终产物,其分解过程主要由2步组成.运用Popescu提出的热分析动力学数据处理方法确定了第2步热分解反应的活化能、指前因子和机理函数.

The thermal decomposition of the copper acetate dihydrate in a static air atmosphere was invest/gated by TG-DTG techniques. The intermediate and residue for each decomposition were identified from TG curve. The kinetic triplet-the activation energy E, the pre-exponential factor A and the mechanism functions f（a ） were obtained from analysis of the TG-DTG curves for thermal decomposition of the second stage by the Popescu method.
