Solute–solvent interactions of glycine, l-alanine, and l-valine in aqueous 1-methyl-3-octylimidazolium chloride ionic liquid solutions in the temperature interval (288.15–308.15)K

Solute–solvent interactions of glycine, l -alanine, and l -valine in aqueous 1-methyl imidazolium chloride ionic liquid solutions in the temperature interval (288.15 to 308.15) K

“…This behavior is in contrast to results reported in our previous findings for ( [emim][Cl] + water + amino acids) [29] and ([moim][Cl] + water + amino acids) mixtures [30]. The negative values have been observed for K /,s which indicate towards decreased compressibility of bulk upon introduction of amino acids.…”

“…The values of S v and S k represent experimental slopes which provide essential information regarding the nature of the solute-solute interactions. The values of V 0 / and S v collectively with K 0 /;s and S k [29,53]. The partial molar properties at infinite dilution represent (solute + solvent) interactions.…”

“…The interactions of type (iii) lead to negative DV 0 / values as the alkyl group has a tendency for hydrophilic-hydrophobic and hydrophobic-hydrophobic group interactions and also the overlapping of cospheres reduces the volume. [29,53]). …”

“…The solvation behavior of amino acids can be accessed by studying the solubility data of ILs and salt mixtures. In previous work, we have studied the density and speed of sound of (IL + water + ester) [25][26][27][28] and (IL + water + amino acid) [29,30] mixtures to understand their mutual interaction behavior. Now, an attempt has been made to understand intermolecular interactions among 1-methyl imidazolium chloride and amino acids.…”

Investigation on solute–solvent interactions of glycine, l -alanine and l -valine in aqueous tetraethylammonium iodide solutions at different temperatures with reference to volumetric and acoustic measurements

“…The values of ܸ ∅ ‫)ݎ݁ݐܽݓ(‬ and ‫ܭ‬ ∅,௦ ‫)ݎ݁ݐܽݓ(‬ for the calculation of partial molar properties at infinite dilution are taken from our previous work [26]. The results obtained are given in table 5 According to the co-sphere overlap model [27], the effect of overlap of the hydration co-sphere is destructive.…”
