“…As several PILs were in a solid state at room temperature, Table S2 only summarizes the density data of 10 PILs which were in a liquid state at room temperature. In order to evaluate the influence of temperature to density of synthesized PILs, the following equation was used to characterize the change law of density with the increase of temperature (Khan et al, 2017; Chen et al, 2018; Prasad et al, 2018b):…”

In order to obtain the regularities of physicochemical properties of hydroxy protic ionic liquids (PILs) and broaden their potential application, a series of 2-hydroxyethylammonium sulfonate-based PILs were synthesized through proton transfer reaction and characterized by NMR and FT-IR and elemental analysis. Their phase transfer behavior ( T m ) and initial decomposition point ( T d ) were characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), respectively. Meanwhile, the regularities of density (ρ), viscosity (η) and electrical conductivity (σ) of synthesized PILs at different temperatures were measured. The results indicated that their physicochemical properties were tightly related with their structures and the interactions between cations and anions. In addition, the dissociation constants (p K a) of synthesized PILs were obtained by acid-base titration, which revealed that all synthesized PILs had p K a exceeding 7 and their cations were the crux of determining the p K a value. Moreover, several synthesized PILs with a low melting temperature also showed potential application in the deoxidation reaction of cyclohexanol, as they had conversion rates approximating 100% and the selectivity of cyclohexane or cyclohexene was about 80%.

Estimation of the liquid phase heat capacity of ionic liquids (ILs) is necessary in order to select and design the optimum ILs for specific industrial applications, particularly those involving thermal storage and heat transfer. Most attempts at estimating the heat capacity (at the constant pressure) of ILs have followed the group contribution model (GCM) approach, but these have involved the use of limited databases and cannot be applied to a wide range of ILs. In this study, an extensive database of over 11500 data points with 273 unique ILs, made up of 155 unique cations and 74 unique anions, was compiled and used to assess three commonly used GCMs. GCM-1 is less complicated than the other two in terms of its mapping parameters but is more restricted in terms of its applicability. GCM-2 and GCM-3 are more complex and have been further improved by incorporating additional functional groups and indirect parameters. The results have shown that GCM-2 and GCM-3 have performed better than GCM-1 in terms of their mean absolute percentage error (MAPE) (2.37% for GCM-1, 2.27% for GCM-2, and 2.17% for GCM-3) and enable heat capacity prediction for a wider range of ILs.

“…It is efficacious against various bacteria and yeasts. 2-Butoxyethanol got approval by Food and Drug Administration (US FDA), to be used as food additives in the both ways direct and indirect, antimicrobial agents, defoamers, stabilizers, preservatives, and adhesives [15][16][17][18]. In order to determine the physical and chemical properties of the liquid system, a number of thermodynamic parameters were computed in light of the experimental results.…”

Understanding the molecular dynamics and intermolecular interaction of liquid mixtures can be greatly aided by ultrasonic study. Sound speed and Density of glycols ethers (phenoxyethanol and butoxyethanol) in solutions of a well-known sugar alcohol (d-Mannitol), were measured using the AntonPaar (DSA 5000 M) at concentrations of (0.02, 0.06, and 0.10) mol.kg−1 and fixed experimental pressures (0.1 MPa) over the entire temperature range (288.15, 293.15, 298.15, 303.15) K. With the experimental data of velocity and density, a number of additional dependent basic acoustic-thermodynamic parameters, namely Vander Waal’s constant (b), intermolecular free length (Lf), acoustic impedance (Z), adiabatic compressibility (β), Rao’s constant (R), and Wada’s constant (W) have been evaluated. Through these parameters, interactions between solutes and their solvents are expressed in terms of solute-solvent interactions. Research is also done on the solute’s capacity to create or destroy structures in a solvent. The inter-molecular interactions amidst the ternary mixture of glycols ethers and d-mannitol in aqueous medium were analyzed.
