β-环糊精与甲基橙包络物热分解反应动力学的研究

Study on the Thermal Decomposition Kinetics of Inclusion Complex of βcyclodextrin and Methyl Orange

采用非恒温热重分析法研究了β－环糊精与甲基橙包络物热分解反应的动力学．实验结果表明，β－环糊精与甲其橙包络物热分解反应为一级反应．用Ｏｚａｗａ（１）法和Ｒｅｉｃｈ法求得热分解反应的活化能分别为１４３．７９ｋＪ／ｍｏｌ和１３９．２６ｋＪ／ｍｏｌ．

The thermal decomposition kinetics of βcyclodextrin and methyl orange has been studied by using nonisothermal thermogravimetry.The experiment result showed that the reaction order of thermal decomposition of βcyclodextrin and methyl orange is the first order.The average activation energy of the thermal decomposition calculated by using Ozawa (1) method and Reich method are 14379 kJ/mol and 13926 kJ/mol respectively.
