“…The authors of both publications calculated the limiting molar volumes of transfer from water to aqueous d -sorbitol solutions for amino acids and they postulated the existence of hydrophilic/polar group interactions in the systems. The same conclusion was reached by Banipal et al who studied volumetric properties of d -sorbitol in aqueous solutions of l -glycine [ 18 ].…”

Apparent molar volumes and apparent molar compressibilities for d-sorbitol in (0.05, 0.1, 0.2 and 0.3) mol·kg−1 aqueous solutions of l-alanine, l-cysteine and l-histidine and NaCl have been determined from measurements of solution density at T = (288.15, 298.15, 308.15 and 318.15) K and sound velocity at T = 298.15 K, as a function of the concentration of the sugar alcohol. The data were used to obtain the limiting apparent molar volumes, limiting apparent molar compressibilities and the corresponding transfer parameters. Limiting apparent molar expansibilities and their second order derivatives and volume interaction coefficients were also estimated. These parameters are discussed in terms of d-sorbitol and co-solute (amino acid or sodium chloride) interactions in aqueous solutions.

“…However, the limiting standard enthalpy of dilution (Δ dil H °) and their corresponding transfer (Δ tr Δ dil H °) values indicate the predominance of (hydrophilic + hydrophilic) interactions at low molalities and temperatures. The ternary solutions of saccharides in l -glycine (aq) and CTAB (aq) solutions also suggested the predominance of (hydrophilic + hydrophilic) interactions.…”

Limiting standard enthalpies of dilution (Δ dil H°) and Jones−Dole viscosity B-coefficients of various polyhydroxy solutes, viz., saccharides, their methyl and deoxy derivatives, and sugar alcohol in 0.05, 0.15, 0.25, and 0.35 mol•kg −1 thiamine HCl (aq) and pyridoxine HCl (aq) solutions have been determined from heat change (q) and viscosity (η) data at T = 288.15−318.15 K and pressure p = 0.1 MPa. The corresponding transfer parameters (Δ tr Δ dil H°, Δ tr B), change in heat capacity (Δ dil C°p ,2,m ), and enthalpic (h AB and h ABB ) and viscometric (η AB and η ABB ) pair and triplet interaction coefficients have also been derived. The dB/dT coefficients have been calculated and discussed in terms of the kosmotropic or chaotropic nature of solutes in aqueous solutions of vitamins. The present results have also been compared with previously reported studies carried out in L-ascorbic acid. 17 Further, NMR spectroscopy has been employed to understand the nature of interactions occurring in ternary solution {polyhydroxy solute + vitamins + 9:1 (w/w) H 2 O−D 2 O} at molality m B = 0.15 mol•kg −1 and T = 300.15 K. The results have been explained in terms of contributions due to hydrophilic−hydrophilic/hydrophobic interactions and H-bonding between solute−solute/cosolute molecules. The effect of stereochemistry and molecular conformations of both polyhydroxy solutes and cosolutes (vitamins) have also been discussed.
