“…From the literature survey, we found that in recent years there are extensive studies of volumetric properties of amino acids in aqueous solution − and in mixed aqueous solutions, − and the protonation constant study of amino acids in mixed aqueous solution, − but very few studies have been done in aqueous saccharide solutions. − …”

Knowledge of thermodynamic properties of amino acids in aqueous medium can provide valuable information about the stabilization mechanism of proteins. In this study, we report the density and speed of sound of some amino acids (2-aminopropanoic acid, 2-amino-3-methylbutanoic acid, 2-amino-4-methylpentanoic acid, and 2-amino-3-phenylpropanoic acid) in aqueous fructose, d-(+)-cellobiose, and d-melezitose solutions (0.1 mol·kg−1) at (293.15, 298.15, 303.15, and 308.15) K. From these data, the apparent molar volume and apparent molar adiabatic compressibility have been evaluated. The partial molar volume, partial molar adiabatic compressibility, and their corresponding transfer functions were calculated. These results were used to interpret the type of interactions occurring in the ternary mixtures using the cosphere overlap model. The concentration and temperature dependence of solute−solute and solute−solvent interactions in the present study was also discussed.

“…In spite of this, the negative Δ tr H 0 values still indicate that electrostatic interaction between glycylglycine and salts is predominant. Comparing the Δ tr H 0 data of glycylglycine with that of glycine 23,24 in the same concentration salt solutions, the more negative Δ tr H 0 values of glycylglycine reflect the stronger interaction between glycylglycine and salts than that of glycine.…”

“…19 However, few authors have studied the behavior of protein model compounds in aqueous oxacid salts solutions. 20−22 As a part of the continuation of our studies on the thermodynamics properties of amino acids and dipeptides in aqueous oxacid salts solutions, 23,24 this work reports the transfer properties of glycylglycine from water to aqueous NaNO 3 , NaClO 4 , and Na 2 SO 4 solutions.…”

Enthalpies of solution and densities of glycylglycine in aqueous solutions of NaNO3, NaClO4, and Na2SO4 were measured at 298.15 K. Standard transfer enthalpies (Δtr H 0), standard transfer partial molar volume (Δtr V ϕ 0), and hydration numbers (N h) have been determined for glycylglycine. All of the Δtr H 0 values are negative in the three salt solutions. The relative order of Δtr H 0 in the same concentration of 1–1 type salts is NaNO3 > NaClO4. The Δtr H 0 in low concentration of Na2SO4 solutions is between the corresponding values in NaNO3 and NaClO4 solutions. With increasing Na2SO4 concentration, the Δtr H 0 values exceed that in NaNO3 solutions. The Δtr V ϕ 0 values are positive and vary in the sequence Na2SO4 > NaNO3 > NaClO4. The results were discussed in terms of various interactions.

We present simple %-level accuracy universal correlations for densities of aqueous electrolyte solutions at 298.15 K and 0.1 MPa. The developed expressions and parameters are based on 1032 experimental density data points for 56 aqueous single electrolyte solutions including chlorides, bromides, iodides, bicarbonates, carbonates, sulfates, nitrates, nitrites, phosphates, hydrogen phosphates, and dihydrogen phosphates. The correlations relate the solution density with "excess" mass fraction of electrolytes in solution. With molar mass and concentrations of electrolytes as input, the correlation yields density results for all 56 electrolytes with the average error of 0.97% and the maximum error of 8.05%. When grouping the electrolytes as either structure making, structure breaking, or structure superbreaking, the correlations yield the average error of 0.59% and the maximum error of 3.45%. The correlations should be very useful in estimating the density of aqueous single and multicomponent electrolyte solutions including high-salinity produced water from oil and gas production.
