摘　　要：利用差热分析(DTA)及变温红外光谱技术测定了季戊四醇-氨基异丁基三醇(PETAM)二元体系的相图。研究表明,在该相图中存在两个低共熔点和一个转晶点,多元醇分子在低温时的有序和高温时的无序是影响二元体系不同相间互溶度的重要因素。The binary systems of polyalcohols have potential use for heat storage. The experimental phase diagram of the binary system pentaerythritol-tris (hydroxymethyl) aminomethane (PE-TAM) was established from room temperature to the liquidation temperature by two techniques: differential thermal analysis (DTA) method and IR spectra at various temperatures. The result shows that the phase diagram includes of two eutectoid invariants and one peritectic invariant. The behavior that polyalcohols are orderded at low temperatures and disordered at high temperatures is the important factor affecting the miscibity in different phases of the binary system.
