Notes:
Summary Results are presented of studies of packings containing copper (II) acetylacetonate (acac), hexafluoroacetylacetonate (hfac), and chloride, chemically bonded via β-dik-etonate groups. The retention parameters retention factor (k) specific retention volume (V g), and molecular retention index (M e) were measured and used to calculate the thermodynamic parameters free energy of adsorption (ΔG a) heat of adsorption (−ΔH a), and entropy of adsorption (ΔS a). These parameters enable, characterization of specific interactions between aromatic and cyclic hydrocarbons, ethers and thioethers and metal complexes chemically bonded, to a silica surface.
