| 摘 要： | 用ＤＳＣ技术研究新戊二醇（ＮＰＧ）、三羟甲基氨基甲烷（ＴＡＭ）及其混合物的固－固相变的动力学，运用Ｋｉｓｓｉｎｇｅｒ及Ｏｚａｗａ方法计算固－固相变的活化能及反应级数，两种方法的结果相符。通过实验数据分析，探讨了活化能随组成变化的规律。

| Abstract: | This paper reports the study of solid solid phase transitions kinetics in neopentylglycol(NPG),2 amino 2(hydroxymethyl) 1,3 propanediol(TAM)and their mixture by using DSC technique.Kissinger and Ozawa methods were applied to determine the activation energy and the reaction order of the solid solid phase transitions.The results of the two methods are in agreement.Through experimental data analysis,the changes of activation energy with the composition of the mixture NPG/TAM were studied. |
