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 -固相变温度和峰温与升温速率呈线性关系
The kinetics of solid - liquid phase transition and solid - liquid phase transition of neopentyl glycol (NPG), trimethylol ethane (PG) and their binary systems were studied by DSC. The activation energy and reaction order of the phase transition were calculated by Kissinger and Ozawa methods. The calculated results of the two methods are consistent. Solid - solid phase transition temperature and peak temperature and the heating rate showed a linear relationship
