Abstract

Solid-phase reactions of silver trifluoroacetate CF₃COOAg with copper, indium, and zinc are studied by thermogravimetry, differential scanning calorimetry, and mass spectrometry. In a temperature range of 358–428 K, the reactions are found to afford trifluoroacetates of these metals without mass loss of the weighed samples. The obtained experimental data make it possible to calculate the enthalpy of formation of copper trifluoroacetate \({{\Delta }_{f}}H_{{298}}^{^\circ }\)(CF₃СООСu, cr) = –1020.5 ± 18.0 kJ/mol.

三氟乙酸银与铜、铟和锌的多相合成。三氟乙酸铜的标准生成焓

摘要

通过热重分析、差示扫描量热法和质谱研究了三氟乙酸银CF ₃ COOAg 与铜、铟和锌的固相反应。在 358–428 K 的温度范围内，反应生成了这些金属的三氟乙酸盐，且称重样品的质量没有损失。获得的实验数据可以计算三氟乙酸铜的生成焓\({{\Delta }_{f}}H_{{298}}^{^\circ }\) (CF ₃ СООСu, cr) = –1020.5 ± 18.0 kJ/mol。
