“…The dielectric properties of mixtures have significant effects on their intermolecular interactions [148]. The static dielectric constant is a measure of the polarity and intermolecular interactions in a solvent [149], which helps to understand the solvation ability of the solvent [150].…”

Valorization of lignocellulosic biomass and food residues to obtain valuable chemicals is essential to the establishment of a sustainable and biobased economy in the modern world. The latest and greenest generation of ionic liquids (ILs) are deep eutectic solvents (DESs) and natural deep eutectic solvents (NADESs); these have shown great promise for various applications and have attracted considerable attention from researchers who seek versatile solvents with pretreatment, extraction, and catalysis capabilities in biomass- and biowaste-to-bioenergy conversion processes. The present work aimed to review the use of DESs and NADESs in the valorization of biomass and biowaste as pretreatment or extraction solvents or catalysis agents.

“…They are associated liquids due to the dipole–dipole and hydrogen bonding interaction. The molecular association process plays a significant and effective role in physical and thermophysical properties of these polar molecules. − The self-association and structural rearrangements of alcohols through hydrogen bonding have been the subject of considerable interest in recent years. − The physicochemical and dielectric properties of pure alkanols and their mixtures have been largely studied by numerous authors. − …”

This study reports the experimental relative permittivity, refractive index, and density data for several polar binary systems containing a cyclic ketone (cyclopentanone) and a series of alkanols from C 2 to C 10 over the entire composition range at T = 298.15 and p = 101.3 kPa. Further study was performed on a polar−nonpolar system composed of cyclopentanone and cyclohexane at the mentioned temperature and pressure. The experimental data were analyzed with various approaches in a consistence framework and in terms of intermolecular interactions between the constituent molecules. The effective and corrective Kirkwood correlation factors were calculated, in order to investigate the H-bond structure formation in the mixtures. The intermolecular interactions were investigated through various excess parameters, namely, excess permittivity, excess refractive index, excess molar volumes, excess Helmholtz energies, and excess Kirkwood correlation factors.

Relative permittivity, refractive index, and density data were experimentally determined for several binary systems (cyclopentanone or cyclohexanone + pentanol isomers) over the entire composition range at 298.15 K and 101.3 kPa for the first time. The selected pentanol isomers were 1-pentanol, 2-pentanol, 3-pentanol, isopentanol, and tert-pentanol. The experimental physicochemical data were used to calculate the various excess quantities. These quantities were applied to interpret the manner of cycloalkanone−pentanol interactions. Excluding the mixtures containing tertiary pentanol, the excess permittivities were found to be negative for all the studied systems. The mixtures containing the weakly associated tert-pentanol display a reverse physicochemical and excess behavior when compared to the systems containing the strongly associated primary and secondary pentanols. The Redlich−Kister equation was used to fit the experimental excess molar volumes. For the studied systems, a negative correlation exists between the excess molar volume (V̅ E ) and excess refractive index (n E ).
