摘　　要：用 DSC技术研究了新戊二醇 ( NPG)、三羟甲基乙烷 ( PG)及其二元体系的固 -固、固 -液相变的动力学。运用 Kissinger及 Ozawa方法计算了相变过程的活化能及反应级数 ,两种方法的计算结果一致。固The paper studies the solid solid、solid liquid phase transitions kinetics in neopentylglycol(NPG),pentaglycerine(PG) and their binary system by DSC.Kissinger and Ozawa methods were applied to determine the activation energy and reaction order of the solid solid、solid liquid phase transitions.The results of two methods are in agreement.A linear relationship was presented between transform temperature or peak temperature and the heating rate.
