摘　　要：多元醇固 固相变动力学的研究能对贮热利用提供理论依据。采用DSC技术研究了三羟甲基乙烷(PG)、季戊四醇(PE)和三羟甲基胺基甲烷(PG)及其PG/TAM、PE/TAM两个二元体系的固 固相变动力学。运用Kissinger及Ozawa方法计算了固 固相变的表观活化能及反应级数,两种方法的计算结果一致,并探讨了活化能与组成变化的规律。The solid-solid phase transitions kinetics in pentaglycerine (PG), pentaecythritol (PE) , 2-amino-2(hydroxymethyl)-1,3-propanediol (TAM) and their binary system was studied by DSC. Kissinger and Ozawa methods were applied to determine the activation energy and reaction order of the solid-solid transitions. The results of two methods are in agreement. Through experimental data analysis, the changes of activation energy with the composition of binary system were studied. The Solid-solid phase transition reaction order of polyhydric alcohols and their binary system at different heating rate one.
