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.

“…Bahadur et al define the S v in terms of the hydrogen bonding interaction. 29 For the hydrogen bonding interaction, the S v values are found to be positive. Thus, our positive results for S v correspond to the hydrogen bonding interactions (among glucose, water, and DEP anion) present in the systems.…”

Binary systems of two ionic liquids (ILs), 1-ethylpyridinium methanesulfonate [C2Py][MeSO3] and choline dihydrogen phosphate [Chol][H2PO4], and water have been experimentally studied. Density, viscosity, electrical conductivity and proton activity have been measured at several temperatures covering all the miscibility range. From density data, isobaric coefficient of thermal expansion was calculated to study the volumetric behavior of the mixtures. All volumetric data were fit using polynomial equations. The Vogel–Fulcher–Tamman (VFT) equation accurately describes the temperature dependence of viscosity for all systems. Systems based on [C2Py][MeSO3] are less dense and viscous than those involving [Chol][H2PO4], making [C2Py][MeSO3] more suitable for absorption systems where pumping cost has a significant importance. Electrical conductivity data were adjusted using the Casteel–Amis equation. Similar trends were found for both systems, although ionic conductivity is higher for [C2Py][MeSO3] + H2O mixtures. The relation between viscosity and electrical conductivity was also explored. According to Walden plots, ILs present low ionicity; however, internal friction and ionic concentration does not seem to be enough to explain the behavior of ionic conductivity and IL concentration. Proton activity measurements show different tendencies with molar fraction of each IL, [C2Py][MeSO3] leads to lower pa H+ values than [Chol][H2PO4] in the binary mixtures. Results of ionic conductivity and proton activity suggest a higher corrosive potential of [C2Py][MeSO3] + H2O; however, a further analysis needs to be done to evaluate this risk in absorption systems. Finally, a composition analysis based on ionic chromatography (IC) was carried out to obtain insight about its effect on their physicochemical properties.

In this present study, the interaction between a carboxylic acid and ionic liquids, in terms of their binary mixtures and corresponding thermo-physical properties, was investigated. Here, the novel ionic liquid (IL) [EPMpyr] + [Cl] − was synthesized, and it has been mixed with ethanoic or propanoic acids. The influence of the epoxy group in this ionic liquid was more strongly affected with the acids, and their physicochemical properties at varied temperatures are discussed in term of density (ρ), viscosity (η), speed of sound (u), and refractive index (n) measurements. The density (ρ), speed of sound (u), viscosity (η), and refractive index (n) of the IL, ethanoic acid, propanoic acid, and their corresponding binary mixtures {[([EPMpyr] + [Cl] − (1) + ethanoic or propanoic acid (2)} have been measured at T = (293.15−313.15) K and at P = 0.1 MPa. The theoretical thermodynamic properties of excess molar volumes (V m E ), isentropic compressibility (k s ), deviation in isentropic compressibility (Δk s ), and intermolecular free length (L f ) are calculated using experimental density and speed of sound data. The V m E and Δk s values for both binary mixtures were found to be negative over the entire mole fraction range of composition at all the investigated temperatures. These results suggest the existence of specific interactions between components in the molecules. The experimental data could be helpful to understand the molecular interactions between the IL and carboxylic acid combinations. The experimental data were fitted to the Redlich−Kister polynomial equation.
