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.
