Study on Thermal Decomposition Kinetics of the Potassium Oxalate Monohydrate
摘要/Abstract
摘要：
用TGDTG技术研究了一水合草酸钾在静态空气中的热分解过程.根据TG曲线确定了热分解的中间产物及最终产物.运用Popescu的热分析动力学数据处理方法,确定了第1步和第2步热分解反应的动力学三因子,即表观活化能E、指前因子A和机理函数f(α).
Abstract：
The thermal decomposition of the potassium oxalate monohydrate in a static air atmosphere was investigated by TG-DTG techniques. The intermediate and residue for each decomposition were identi-fied from TG curve. The kinetic triplet2the activation energy E,the pre-exponential A and the mechanism functions f(α) were obtained from analysis of the TG-DTG curves for thermal decomposition of the first stage and the second stage by the Popescu method.
