用ＤＳＣ研究了ＴＥＡＮ－Ｈ２Ｏ二元体系的低温热行为，建立了该体系的液化温度与组成关系的ＴＸ－二元相图和低共熔物表观熔融焓与组成关系的ＨＸ－二元相图。发现该二元体系是一个典型的具有简单低共熔物的二元体系，其低共熔温度为－１６．２℃，低共熔物组成为ＴＥＡＮ－Ｈ２Ｏ＝１０／９０（ｍｏｌ／ｍｏｌ）。过冷体系在升温过程中有结晶现象，其结晶焓与ＴＥＡＮ浓度有线性关系。ＴＥＡＮ浓度小于２５ｍｏｌ％时，具有玻璃化转变过程，其转变温度不随试样浓度的改变而变化，平均值为－９１．２℃，而在ＴＥＡＮ浓度大于２５ｍｏｌ℃时，未发现玻璃化转变。
The low-temperature thermal behavior of TEAN-H2O binary system was studied by DSC. The relationship between the liquefaction temperature and the composition of TX-Binary phase diagram and the apparent fusion enthalpy of the eutectic was established. The HX-binary phase Figure The binary system was found to be a typical binary system with a simple eutectic with a eutectic temperature of -16.2 ° C and a composition of TEAN-H2O = 10/90 (mol / mol) . Subcooled system has the phenomenon of crystallization during the heating process, and the crystallization enthalpy has a linear relationship with TEAN concentration. When the concentration of TEAN is less than 25mol%, it has the glass transition process, the transition temperature does not change with the sample concentration, the average value of -91.2 ℃, and TEAN concentration greater than 25mol ℃, no glass transition was found.
