The formation of NADESs was confirmed using DSC and FT-IR analyses. The basic physical properties of the prepared NADESs including refractive index, density, conductivity, and viscosity were experimentally measured at different temperatures ranging from 288.15 to 328.15 K. The pH measurements of the NADESs at ambient temperature showed that all samples are acidic (pH ≈ 3–4). It was found that the conductivity and refractive index of the NADES samples increase with rising temperature, while their viscosity and density decrease. The temperature dependence of the physical properties of the prepared solvents was analyzed using suitable linear (simple or polynomial) models. Moreover, theoretical studies based on density functional theory (DFT) were conducted to better understand the structure of the NADES compounds, their intermolecular interactions, stability and thermodynamic characteristics.
