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

摘要/Abstract

摘要:

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.

Abstract:

The thermal decomposition of the copper acetate dihydrate in a static air atmosphere was investigated by TG-DTG techniques. The intermediate and residue for each decomposition were identified from TGcurve. The kinetic triplet2the activation energy E,the pre-exponential factor A and the mechanism functions f (α ) were obtained from analysis of the TG 2DTGcurves for thermal decomposition of the second stage by the Popescu method
