“…As stated earlier, alkoxyethanols are associated via inter-and intramolecular hydrogen bonding. The values of the excess molar volumes, , are reported to become more negative when the alkyl chain length of the alkoxyethanol increases [41]. Our results however suggest that other factors, such as the differences in the molecular sizes of the component molecules, also play a role in the mixing behavior of the component solvents.…”

Densities of binary mixtures of 2-methoxyethanol (2-MeO-EtOH) and 2-ethoxyethanol (2-EtO-EtOH) with hexylamine (HLA), diethylamine (DEA), triethylamine (TEA), tert-butylamine (TBA), aniline (ANL), and benzylamine (BLA) have been determined at varying compositions of the alkoxyalkanols at 298.15 K. The excess molar volumes, VE, of the binary mixtures were calculated from the experimental density data of the mixtures and the component single solvents. The calculated excess molar volumes were fitted into the Redlich-Kister polynomial to obtain the fitting coefficients and standard deviations. The excess molar volumes of the binary mixtures of all the solvent systems investigated were negative over the entire range of the solvents composition. The negative values were attributed to stronger hydrogen bond formations between the unlike molecules of mixtures than those between the like molecules of the pure components. The magnitude of the excess molar volumes of the binary mixtures of 2-methoxyethanol and the aliphatic amines were in the order TBA > TEA > DEA > HEA. For the two aromatic amines, the magnitudes were in the order BLA > ANL. For binary mixtures of the amines and 2-ethoxyethanol, the magnitudes were in the order DEA > TEA > TBA > HEA at compositions where the mole fraction of 2-EtO-EtOH was ≤0.5 and TBA > TEA > DEA > HEA above 0.5 mole fraction of 2-EtO-EtOH.

“…We have studied previously the nature and type of intermolecular interactions in binary liquid mixtures containing alkoxyalcohols or polyethylene glycols in terms of the mixing parameters such as excess molar volume, excess molar refractivity, deviations in relative permittivity, deviations in viscosity, and deviations in isentropic compressibility [1][2][3][4][5][6]. The 2-propoxyethanol (PE), diethylene glycol (DEG), triethylene glycol (TEG), and tetraethylene glycol (TET-RAEG) have been used in the present studies.…”

“…There was an increase in negativity with decreasing in the molecular weight of components in mixtures. This increase in negativity can be attributed mainly to the association between the O atom in tetrahydrofurfuryl alcohol (non-associated) and with (-OH) group from C1 to C4 in carboxylic acids by the genesis of hydrogen bonds, and the interactions between unlike molecules were stronger than interactions between like molecules [27][28][29].…”

At the temperature 298.15 K, some physical properties such as: refractive indices (nD), viscosities (η) and densities (ρ) were studied in four liquid-liquid mixtures: carboxylic acids (HCOOH, CH3COOH, CH3CH2COOH and CH3CH2CH2COOH) with tetrahydrofurfuryl alcohol (THFA) with the identified configuration set. These empirical data were utilized to estimate the excess molar volumes (Vm E ), refractive index perversions (∆R), viscosity deviations (η E ) and excess molar Gibbs free energy (∆G *E ). Values of Vm E , η E , ∆G *E and ∆R were plotted versus mole fraction of tetrahydrofurfuryl alcohol. In all cases, the values of Vm E , η E , ∆G *E and ∆R that obtained in this study were found to be negative at 298.15 K. The excess parameters were applied in the Redlich-Kister equation by utilizing multi-parameter coefficients that concluded binary coefficients and in respect to the standard deviation. The difference of these characteristics with the formation of binary liquid systems indicates the absence of bipolar bond, variation in the shape and size of component molecules, hydrogen bonding and dipolar interaction among unlike molecules.
