The changes in the molecular interactions of 1-ethyl-3-methylimidazolium diethyl phosphate ionic liquid in aqueous and aqueous d-glucose solutions are being investigated through the thermodynamic and compressibility parameters. The purpose of this research is to give insight into details about the thermophysical aspect of cellulose dissolution. Toward this objective, we have evaluated the thermodynamic and compressibility parameters of 1-ethyl-3-methylimidazolium diethyl phosphate in aqueous and in 0.06 and 0.12 mol kg–1 aqueous d-glucose solutions in the concentration range of 0.02 to 0.14 mol kg–1 at different temperatures, i.e., T/K = (288.15 to 318.15). The various derived parameters including the apparent molar volume of solute (V ϕ), limiting apparent molar volume of solute (V ϕ 0), limiting apparent molar expansivity of solute (E ϕ 0), isentropic compressibility of solution (κs), apparent molar isentropic compressibility of solute (K s,ϕ), limiting apparent molar isentropic compressibility of solute (K s,ϕ 0), limiting apparent molar volume of transfer (Δtr V ϕ 0), and limiting apparent molar isentropic compressibility of transfer (Δtr K s,ϕ 0) have been calculated with the help of experimental density (ρ) and sound velocity (c) data. The kosmotropic nature of [EMIm][DEP] has been proven using Hepler’s constant (∂2 V ϕ 0/∂T 2). These estimated experimental values shed light on the numerous physicochemical interactions that exist in the systems and show the presence of significant attractive interactions among 1-ethyl-3-methylimidazolium diethyl phosphate ionic liquid and d-glucose.

Volumetric and compressibility properties offer us insight into the kinds of interactions existing in the solutions. Taking that into consideration, we measured the densities and sound velocities of 1-(2-hydroxyethyl)-3-methylimidazolium chloride in aqueous and 0.05 mol•kg −1 aqueous L-alanine solutions within the concentration ranges of 0.01−0.14 mol•kg −1 at different temperatures (293.15, 298.15, 303.15, 308.15, 313.15, and 318.15 K) and atmospheric pressure. These experimental results are used to determine the apparent molar volume of solute (V φ ), apparent molar compressibility of solute (K S,φ ), limiting apparent molar volume of solute (V φ 0 ), and limiting apparent molar compressibility of solute (K S,φ 0 ) for 1-(2-hydroxyethyl)-3-methylimidazolium chloride in aqueous and 0.05 mol•kg −1 aqueous L-alanine solutions. The transfer partial molar volume (Δ tr V φ 0 ) and compressibility (Δ tr K S,φ 0 ) of 1-(2-hydroxyethyl)-3-methylimidazolium chloride from water to aqueous L-alanine solution were also computed. The outcome of the study reveals that the interaction between [HEMIm][Cl] in both water and L-alanine increases with the rise in temperature. The positive values of transfer parameters are observed, which indicate that the ion−hydrophilic/hydrophilic− hydrophilic interactions predominate over hydrophobic−hydrophobic interactions. The positive Hepler's constant, i.e., (∂ 2 V φ 0 /∂T 2 ) P , values imply that [HEMIm][Cl] behaves cosmotropically in all binary and ternary studied systems. Additionally, the optimization and energetics of various framed structural systems of the concerned ionic liquid are computed using Gaussian to characterize various intermolecular interactions.

The present study employed volumetric and compressibility methods to investigate the intermolecular interactions of 1,3-dimethylimidazolium methyl sulfate, i.e., [MMIm]-[MeSO 4 ] ionic liquid in both aqueous and aqueous L-alanine solutions. Density (ρ) and sound velocity (c) for [MMIm]-[MeSO 4 ] in two different systems such as the binary system ([MMIm][MeSO 4 ] in water) and the ternary system ([MMIm]-[MeSO 4 ] in 0.05 mol kg −1 aqueous L-alanine solution) were measured within a temperature range of 288.15−318.15 K at intervals of 5 K over the concentration range of 0.03−0.15 mol kg −1 . We calculated various parameters such as the apparent molar volume of solute (V ϕ ), the limiting apparent molar volume of solute (V ϕ ο ), the experimental slope (S v ), the isobaric thermal expansion coefficient (α), the transfer limiting apparent molar volume of solute (Δ tr V ϕ 0 ), the isentropic compression of solution(κ S ), the apparent molar isentropic compression of solute (K S,ϕ ), the partial molar isentropic compression of solute (K S,ϕ 0 ), the transfer partial molar isentropic compression of solute (Δ tr K S,φ 0 ), and Hepler's constant (∂ 2 V ϕ 0 /∂T 2 ) by using the experimental ρ and c data. The outcomes are elucidated in terms of interactions between the solute−solute and solute−solvent in the studied systems.
