| 摘 要： | 文章合成了Lu(NO3)3(C2H5O2N)4.H2O,用红外和元素分析对其进行了表征。用高精度全自动绝热量热仪,测定了该配合物80-382 K温区的热容, 利用实验热容数据, 根据热容与焓、熵的热力学关系, 求出了配合物85-350 K温区内每隔5 K相对于298.15K的标准热力学函数(HT - H298.15)m和(ST - S298.15)m.在80-350 K温度区间内,配合物的热容随温度升高而增大,没有相转移点和热力学吸收峰的出现,该配合物在此温度区间内是稳定存在的。

| Abstract: | A complex of Lutetium nitric acid coordinated with 2-Aminoacetic acid (C2H5O2N), Lu(NO3)3(C2H5O2N)4.H2O was synthesized and characterized by IR and elements analysis. The low-temperature heat capacities of the complex was measured with an automatic adiabatic calorimeter from T = 80 to T = 382 K, and the thermodynamic functions HT -H298.15] and ST -S298.15] were derived based on the heat capacity measurements in the temperature range from T = 85 K to T = 350 K with temperature interval of 5 K. In the temperature range of 80-350 K, the heat capacities increased in a smooth and continuous manner and no phase transition or thermal anomaly occurred. Therefore, the complex was stable in the above temperature range. |
