Solvatochromism in Mixtures of Hydrogen Bond Acceptor (HBA) Solvents with Water

“…[29a,35] In addition, the heat of interaction of NA in DMSO/water mixtures is exothermic over the entire composition range. [108] This is in contrast to the dissolution thermodynamics of NA in alcohol/water and other mixtures. [37,38,107,109] The result for DMSO/water mixtures in Figure 5 is also in full agreement with older data from Catalán [101b] and recent results from Jabbari (Tab.…”

Preferential Solvation of Phenol in Binary Solvent Mixtures. A Molecular Dynamics Study

“…For atomic or molecular ions the preferential solvation in mixed liquids may sometimes become even selective. , Experimental evidence for selective solvation of ions in mixed solvents comes from electrochemical and spectroscopic studies. , The selective solvation phenomenon has received much attention, particularly after measurements by Strehlow and Koepp in the late 1950s. Many theoretical attempts to explain selective solvation are found in the literature based on electrostatic, thermodynamic, and statistical mechanical arguments.…”

“…Among the more technical applications, there are problems in hydrometallurgy of copper, silver, and gold, where preferential solvation is used to refine or regain precious metals from solutions of their salts. The reader is referred to excellent books and review articles concerning preferential and selective solvation. − , …”

“…The reader is referred to excellent books and review articles concerning preferential and selective solvation. [1][2][3][4][5][6]8 Various calorimetric approaches to study the preferential solvation of nonelectrolytes in mixed solvents are discussed by Korolev,9 including cases where the composition dependence of enthalpy in binary mixtures is described by the Redlich-Kister equation. 10 An exact solution is found for the equation of the extended coordination preferential solvation model.…”

Solvation of inorganic complexes: transfer chemical potentials for mono- and bi-nuclear cobalt(III) complexes to methanol + water mixtures

“…[Co(en) 2 (SCH 2-CO 2 )] + [22], to binuclear species such as [(H 3 N) 3 Co (l-OH) 3 Co(NH 3 ) 3 ] 3+ [23] and the mixed metal complex [(en) 2 Co(l-pzc)Fe(CN) 5 ] ) [24]. 1 Such studies have provided information on solvation and preferential solvation [25] and on medium effects on reactivity, as for example in aquation of the triol complex [26] [27], and intramolecular electron transfer within the mixed valence complex [(en) 2 Co(l-pzc)Fe(CN) 5 ] ) [24]. In this present paper we report the results of our study of solubilities, transfer chemical potentials, and solvation of further mononuclear, and a number of doubly bridged and triply bridged binuclear, cobalt(III) complexes in methanol + water mixtures.…”
