Abstract
The thermodynamic characteristics of silver perfluorobenzoates C6F5COOAg·0.5C6F5COOH and C6F5COOAg were studied by thermogravimetry, differential scanning calorimetry, and mass spectrometry. It was found that vaporization of these compounds occurs incongruently to give metallic silver and C6F5COOH, C12F10, CO2, and C18F14 molecules. Using the 2nd and 3rd laws of thermodynamics, the standard enthalpy of formation of silver perfluorobenzoate was found to be \({{\Delta }_{{\text{f}}}}H_{{{\text{298}}}}^{^\circ }\)(C6F5COOAg, cr) = –1195.6 ± 15.7 kJ/mol and the standard enthalpy of formation of the pentafluorobenzoic acid radical was estimated to be \({{\Delta }_{{\text{f}}}}H_{{{\text{298}}.{\text{15}}}}^{^\circ }\)(C6F5COO•, cr) = –878.6 ± 25.0 kJ/mol.
