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

AbstractThis 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 Vϕ (apparent molar volume), (apparent molar volumes at infinite dilution), and calculated speed of sound statistics used to determine Kϕ,s (apparent molar isentropic compression), Ks (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.
