Structural elucidation of ternary mixtures of L-valine/glycyl-L-valine and water + 1-decyl-3-methylimidazolium bromide: Apparent molar properties at infinite dilution and expansivities

Abstract

This work comprises ternary systems of water + SAIL,1-decyl-3-methylimidazolium bromide, and (S)-2-Amino-3-methylbutanoic acid generally identified as L-valine/ (S)-2-(2-Aminoacetamido)-3-methylbutanoic acid usually described as glycyl-L-valine, densities, and sound speed data have been computed at four operating temperatures, i.e., 288.15 to 318.15 K. Calculated density data have utilized for calculation of various thermodynamic parameters like V_ϕ (apparent molar volume), $V_{\varphi }^0$ (apparent molar volumes at infinite dilution), and calculated speed of sound statistics used to determine K_ϕ,s (apparent molar isentropic compression), K_s (partial molar isentropic compression at infinite dilution). In our systems, the hydrophilic-ionic interactions that are produced by co-sphere overlap models are predominant. The Hepler's constant is used to analyze the solute's capacity to create or destroy solvent structures. The interaction parameter is computed using the McMillan-Mayer theory. Understanding structure-making, solvation characteristics, and numerous modifications in the ternary system of L-valine/Glycyl-L-valine, water, and [C₁₀MIm] [Br] is aided by a variety of thermodynamic factors.
