“…The conformational behavior around the C-C bond and C-O bonds in the oxyethylene chain in water suggests the presence of several types of hydrogen bonds between the molecules of amphiphile and water. 3 The positive values of the viscosity deviations suggest that the interaction forces through hydrogen bonding play an important role. …”

Densities and viscosities have been measured as a function of composition for the binary liquid mixture of diethylene glycol monobutyl ether CH 3 (CH 2 ) 3 O(CH 2 ) 2 O(CH 2 ) 2 OH + water in the temperature range from (293.15 to 333.15) K at atmospheric pressure. Densities were determined using a capillary pycnometer. Viscosities were measured with Ubbelohde capillary viscometer. From the experimental data, the excess molar volumes V E and viscosity deviations δη were calculated. This binary system shows negative deviations in excess molar volumes from the ideal behavior. Excess molar volumes and viscosity deviations were correlated by the Redlich-Kister type equations to obtain their coefficients and standard deviations.

The density (ρ), speed of sound (u), and viscosity (η) of the binary mixtures of (diethylene glycol monoethyl ether (carbitol) and water, ethanol, N,N-dimethylformamide) have been measured in full concentration range at T = 288. 15, 298.15, 308.15, and 318.15 K and p = 0.0868 MPa. Using the experimental data, the molar volume (V m ), excess molar volume (V m E ), isentropic compressibility (κ s ), excess molar isentropic compressibility ( s,m E κ ), and viscosity deviation (Δη) were calculated. The most negative values of V m E and s,m E κ and positive values of Δη obtained for the carbitol + water mixture are indicative of the strong interactions between different components relative to two other systems. The values of ρ, V m , and κ s for the studied mixtures were correlated using the Jouyban−Acree model with high accuracy. Furthermore, the obtained values of V m E , s,m E κ , and Δη were described by the Redlich−Kister equation and reasonable standard deviations were obtained.

“…Marcus and coworkers (Marcus, 1985;Hefter et al, 2002) compiled data for the standard enthalpies and entropies of transfer of ions and electrolytes and G 0 t of cations (Kalidas et al, 2000) from water to mixed aqueous-organic solvents published prior to 1996 (or later in some cases), and critically evaluated those values in terms of current views of ion solvation. More data have been reported since then (Gregorowicz et al, 2000;Gulaboski et al, 2002;Kamienska-Piotrowicz, 2005; Piekarski and Kubalczyk, 2005;Prasad and Sangaranarayanan, 2003;Rais et al, 2006;Scholz and Gulaboski, 2005;Scholz et al, 2003;Wilke and Zerihun, 2001). Parfenyuk and coworker (Chankina and Parfenyuk, 2004) determined the Gibbs energy of transfer Na + and K + ions from water into a mixed H 2 O + DMF, of Na + and Cl − into mixtures of water and protic (alcohols) and aprotic (Ac and AN) solvents (Parfenyuk, 2005), and of Ca 2+ into H 2 O + Ac mixtures (Chankina and Parfenyuk, 2006).…”

Most of what is known about the environmental fate and transport of contaminants comes from studies of dilute, aqueous solutions. Theoretical and practical aspects of hydrophobic organic contaminants in aqueous mixtures of organic solvents are well developed, but relatively little attention has been paid to those situations where inorganic contaminants such as metals, water, and organic solvents occur simultaneously. The authors discuss changes in solution properties accompanying the addition of organic solvents. They review more than 500 references to available data on ion solvation, solubility, activity, acidity, pairing, and pH in electrolyte and electrolyte-free solvent mixtures and tabulate selected experimental values. Whenever available, equations developed to estimate these properties are given and their applications and limitations described. The implications of the progress in mixed-solvents solution chemistry on contaminant behavior and transport are described. Major limitations to the study of inorganic contamination in mixed solvents include the absence of complete and comprehensive data (e.g., type of ionic species, activity coefficients, solubility constants) that characterize solute and solvent properties in these mixtures and the indefinite number of possible solute and solvent combinations. The generation of models predicting such data from easily measured benchmark solute and solvent properties is a major challenge. The availability of such database and models may open the field for environmental engineers and soil scientists to study the basic chemical processes and mechanisms of metal contamination in complex multicomponent systems.
