Relative permittivities, refractive indices, and densities were measured for binary liquid mixtures of cyclohexanone with 1-alkanols (ethanol, 1-butanol, 1-hexanol, 1-octanol, and 1-decanol) in the mole fraction range of (0 ≤ x 2 ≤ 1) at T = 298.15 and p = 101.3 kPa. Another comparative dielectric study was performed on the (cyclohexanone or cyclopentanone + cyclohexanol or cyclohexane) mixtures at the mentioned temperature and pressure. The experimental data were analyzed in terms of the various approaches in order to obtain information about the intermolecular interactions and the mixture structure. The excess properties of different physical quantities confirm the formation of hydrogen-bond structure in these mixtures. For the studied systems, negative excess permittivities and excess Kirkwood correlation factors were obtained, indicating a reduction of the number of effective dipoles in the binary mixtures.

“…So when the mixing of solvent is assumed to be ideal, the polarity of solvent can be expressed by the permittivity constant. According to the permittivity of acetic acid, ethanoic anhydride, and tetrachloromethane, the permittivity of the mixed solvent is determined by the following formula. − The ε mix is the permittivity constant of the mixed solvent, the ε is the permittivity constant of the pure solvent, and w is the mass fraction in the mixture solvent. The results of permittivity in the solvent systems were summarized in Table .…”

The solid−liquid equilibrium (SLE) of glutaric anhydride in three pure solvents, tetrachloromethane, acetic acid and ethanoic anhydride, and three binary solvents of acetic acid + tetrachloromethane, ethanoic anhydride + (tetrachloromethane/ acetic acid) and a ternary solvent of tetrachloromethane + acetic acid + ethanoic anhydride solvent systems was measured by dynamic method at a temperature range from 278.45 K to 324.45 K under atmospheric pressure. It turns out that the solubility of glutaric anhydride increases with the temperature increasing in all selected solvents. Moreover, it is interesting that the solubility of glutaric anhydride in two binary solvents (acetic acid + tetrachloromethane, ethanoic anhydride + tetrachloromethane) and ternary solvents mixtures (tetrachloromethane + acetic acid + ethanoic anhydride) was affected more by the decrease of mass fraction of tetrachloromethane at a given temperature. The mass fraction of added ethanoic anhydride had a smaller effect on the solubility of glutaric anhydride in the binary solvent of ethanoic anhydride + acetic acid at T = (279.45 to 314.45) K. The experimental data of solubility were correlated by the λh equation, the Apelblat equation, and nonrandom two liquid equation. All equations can be well applied, and the relative average deviation of the Apelblat equation is less than 0.05. In addition, the thermodynamic properties of the mixing processes in all selected solvents were calculated and discussed based on the nonrandom two-liquid model.

“…In this work, a combination of the DFT hybrid functional B3LYP , with the basis set 6-311++G was used. The molecules were considered to be in a cavity within a liquid solvent composed of molecules of their own, and solvation was described according to the Polarizable Continuum Model (PCM). − This model is used to simulate the solute cavity via a set of overlapping spheres and requires the knowledge of dielectric constants, refractive indices, densities, and molar masses for each chemical species, which can be seen in Table S2, − in the Supporting Information. In addition, after the geometry optimization, a population analysis of the electrons was performed using the Natural Bond Orbital (NBO) function to determine orbital electronic densities and the consequent electrical charge distribution.…”
