| 摘 要： | 在水-丙酮混合溶剂中合成了未见文献报导的Zn(Thr)Ac2?2H2O固态配合物,通过化学分析、元素分析、IR、XRD和TG-DTG等对其组成、结构及热稳定性进行了研究.用微量热法测定了配合物在298.15 K时在纯水中的溶解焓,计算了Zn(Thr)2＋(aq,∞)和Zn(Thr)Ac2?2H2O(s) 的标准摩尔生成焓分别为(955.24±5.70) kJ?mol－1和(-570.92±5.71) kJ?mol－1.

| Abstract: | The complex of Zn Ac2?2H2O and Threonine was prepared in the mixed solvent of water - acetone, the composition of the complex was identified as Zn(Thr) Ac2?2H2O by chemical, elemental analyses. The structure and thermal stability of the title complex were investigated by IR, XRD and TG - DTG. Enthalpy of solution of the complex was determined at 298.15 K in water by microcalorimetry.Standard molar enthalpy of formation of Zn(Thr)2＋(aq,∞) and that of Zn(Thr) Ac2?2H2O (s)were calculated to be (955.24 ± 5.70) kJ?mol-1 and (-570.92±5.71) kJ?mol-1,respectively. |
