Zinc perfluorocyclohexanoate (C<sub>6</sub>F<sub>11</sub>COO)<sub>2</sub>Zn: synthesis, vapor formation and evaluation of thermodynamic characteristics

The heterophase reaction of interaction of silver perfluorocyclohexanoate with zinc was studied by TG, DSC and mass spectrometry. It was found that as a result of interaction in the temperature range of 320–520 K, solid zinc perfluorocyclohexanoate is formed and an intramolecular reaction of zinc fluoride formation occurs. The obtained experimental data allowed us to calculate the standard enthalpies of formation of the solid zinc complex ΔfН°298.15 = –5693 ± 29 kJ/mol, sublimation and formation of dimeric molecules Zn2(C6F11COO)4 ΔsН°Т = = 190±15 kJ/mol, ΔfН°Т = –11196 ± 40 kJ/mol.
