Solvation Properties of Branched-Chain Amino Acids in Aqueous Solutions of 1-Dodecyl-3-methylimidazolium Bromide at Different Temperatures: Volumetric and Acoustic Measurements

Abstract

In terms of solute–solute and solute–solvent interactions, thermodynamic properties help characterize the structure and behavior of solutions. To identify the solute–solvent interactions, experimental density and speed of sound data at (288.15 K–318.15 K) at a 10 K interval have been measured for the aqueous mixtures of branched-chain acetyl substituted l-glycine and l-leucine with ILs. The measured data have been used to determine the apparent molar volume (V ϕ), the partial molar volume, and standard partial molar volumes of transfer, molar isentropic compression, and partial molar isentropic compression of transfer. Also, both these properties have calculated pair and triplet interaction coefficients. Understanding mixing effects and other complex biological processes will be aided by the thermodynamic parameters discovered from the hydrophilic head of the amino acids and the alkyl group of the long-chain ILs.

Apparent Molar Properties of 1-Dodecyl-3-methylimidazolium Bromide Ionic Liquid in the Presence of Aqueous Solution Containing Glycyl-L-X (X = Alanine and Phenylalanine) Dipeptides

“…We investigated the temperature sensitivity of ( V ϕ 0 ) through the application of the general polynomial equation utilized in our previous research Table outlines the constants ( a, b , and c ) specific to glycyl- l -alanine and glycyl- l -phenylalanine in an aqueous solution of [C 12 MIm] Br.…”

“…They provide insightful information about the interactions between solutes and solvents throughout the solution phase. Understanding the interactions between solute and solvent molecules in mixtures is facilitated by focusing on two fundamental thermophysical properties: volume and compressibility. , Three imidazolium-based ILs, ranging from [C 6 mim]­[Br] to [C 10 mim]­[Br] to [C 12 mim]­[Br], were the subject of a thorough study of interactions that we carried out in our previous work. − The results of these systems showed that the length of the alkyl chain in the IL affects both the volumetric and acoustic parameters. Notably, cations that were recognized as kosmotropes or structure-forming agents had alkyl chain lengths of n ( C ) = 6, 10, and 12.…”
