HAN-TEAN-H_2O 三元体系的相变及其相图

The phase transition and phase diagram of the HAN TEAN H 2O ternary system

用ＤＳＣ研究了ＨＡＮ－ＴＥＡＮ－Ｈ２Ｏ三元体系的低温热行为，建立了该体系低温下相变与组分关系的相图。考察了玻璃化转化温度随ＨＡＮ／ＴＥＡＮ比例的变化规律。发现了三元体系的溶液性质在ＨＡＮ－ＴＥＡＮ比率较大时，与ＨＡＮ－Ｈ２Ｏ二元体系相似，而在ＨＡＮ／ＴＥＡＮ比率较小时，则与ＴＥＡＮ－Ｈ２Ｏ二元体系相似。

The low temperature behaviour of the ternary system has been investigated by DSC and a phase diagram for correlation of the phase transition with the composition was constructed. The changes of glass transition of the system with HAN/TEAN ratio have been observed. It is found that the property of solution of the ternary system is similar to that of the binary system of HAN H 2O for the higher ratio of HAN/TEAN and the property to that of the binary system of TEAN H 2O for the low ratio of HAN/TEAN.
