摘　　要：用ＤＳＣ法研究季戊四醇－新戊二醇（ＰＥ－ＮＰＧ），三羟甲基乙烷－新戊二醇（ＰＧ－ＮＰＧ），季戊四醇－２－氨基２－甲基１，３丙二醇（ＰＥ－ＡＭＰ），三羟甲基乙烷－２－氨基２－甲基１，３丙二醇（ＰＧ－ＡＭＰ）和三羟甲基氨基甲烷－新戊二醇（ＴＡＭ－ＮＰＧ）五个多元醇二元体系的固一固相变。这些二元固体溶液的转变温度和转变热与其组成有依赖关系。研究结果可以指导选择贮热材料的组成。SC method was used to study the solid-solid transition of mixtures of the polyols pentaerythritol(PE). pentaglycerine (PG). neopentylglycol (NPG). 2-Amino 2-methyl 1, 3 propaneoliol (AMP) and Trihydroxy methyl-aminomethane (TAM). Values of temperatures and heats of transition for the PE/PG. PG/NPG. PE/AMP. PG/AMP, TAM/NPG binary systems were given.These five compoands and their binary mixtures absorbed heat in the range of 126 to 270 kJ kg-1 during solid state transformations at temperature from 31℃ to 185℃.Our calorimetric results showed that these polyols mixtures availble for different applications.
