在水 丙酮混合溶剂中合成了Zn(Met)Ac2 ·H2 O固态配合物 ,通过化学分析、元素分析、IR、DSC和TG DTG对其组成、结构及热稳定性进行了表征。得出其脱水过程和分解过程的焓变分别为 15 30J/ g和35 7 80J/ g。用转动弹热量计测得其恒容燃烧能ΔcE为 (- 6 4 72 11± 2 2 0 )kJ/mol,计算得其标准燃烧焓ΔcH0m 和标准生成焓ΔfH0m 分别为 (- 6 4 75 2 1± 2 2 0 )kJ/mol和 (- 4 2 9 0 4± 2 5 9)kJ/mol。
The solid state Zn (Met) Ac2 · H2O complexes were synthesized in water-acetone mixed solvents. Their chemical compositions, elemental analyzes, IR, DSC and TG-DTG were used to characterize their structures, thermal stability and stability. The enthalpy change of dehydration process and decomposition process are 15 30J / g and 35 7 80J / g, respectively. The constant heat capacity ΔcE (- 6 4 72 11 ± 2 2 0) kJ / mol was measured with a rotating bomb calorimeter. The calculated standard enthalpy of combustion ΔcH0m and standard enthalpy of formation ΔfH0m were (- 6 4 75 2 1 ± 2 2 0) kJ / mol and (- 4 2 9 0 4 ± 2 5 9) kJ / mol.
