Abstract
Hydrophilic contributions to thermodynamic partition functions of some metal acetylacetonates and monothioacetylacetonates have been calculated by subtracting from the experimental quantities the contributions due to hydrophobic hydration of the chelate in the aqueous phase and to its interactions with the organic phase. These contributions have been evaluated with the use of a simple model describing solubility of hydrocarbons in water, and the theory of regular solutions, respectively. The results obtained are discussed in terms of different hydration of the chelates in their outer coordination sphere and—for coordinatively unsaturated chelates—also in the inner coordination sphere. Especially important are the effects due to replacing oxygen atoms in the acetylacetonate ligands by sulfur, strongly enhancing the extraction of metal chelates.
