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

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.
