“…Various interactions occur in the mixture of alcohols with polar liquids like esters, including charge transfer, H-bonding, and dipole−dipole interactions. 3 These interactions are influenced by the nature of the mixture constituents. 3 Physical properties, such as density, surface tension, and refractive index, of binary mixtures of alcohols, esters, and other solvents/reagents, are important from practical and theoretical perspectives regarding liquid theories.…”

Alkyl levulinate, prepared from the esterification of levulinic acid and n-alcohol, has the potential to be used as a fuel additive. Alcohol has also been used as an additive in fuel to improve ignition and combustion characteristics to a certain extent. For this reason, the properties of mixtures containing these compounds are of particular interest. Herein, measurements of density (ρ), surface tension (γ), and refractive index (n) were conducted for three binary mixtures of methyl levulinate–methanol (ML–M), ethyl levulinate–ethanol (EL–E), and n-butyl levulinate–butanol (BL–B). These properties were measured over the entire range of compositions in 0.1 increments of the molar fraction of the components in the temperature range of T = 298.15–323.15 K and at an atmospheric pressure of p = 0.1 MPa. The experimental data were used to calculate the excess and deviation properties, that is, excess molar volumes (V m Ε), surface tension deviations (Δγ), and molar refraction deviations (ΔR). The V m Ε, Δγ, and ΔR values were fitted to the Redlich–Kister polynomial equation. The V m Ε and ΔR values were negative for all compositions, whereas Δγ exhibited both negative and positive values at different compositions. The molecular interactions of the binary mixtures are discussed from these excess and deviation functions. Furthermore, the Jouyban–Acree model was used for the correlation of properties: density, surface tension, and refractive index of the studied mixtures at different temperatures (T = 298.15–323.15 K). The results are expected to provide fundamental data for understanding the properties of alkyl levulinate as a potential bio-based fuel additive.

“…The excess thermodynamic parameters calculated in liquid mixtures at various temperatures can also provide information on the nature and degree of interaction between the component molecules of the liquid mixtures. The deviation of excess thermodynamic parameters with composition from its ideal behaviour gives a deep insight into the various other dynamic processes that occur in the solutions [10][11][12][13][14][15][16][17][18][19]. In the present paper, we report on the results of nature of molecular interactions between the molecules of the binary mixtures of methylacetate (MA) and ethylacetate (EA) in 2-methoxyethanol (2ME) using excess thermodynamic parameters like excess adiabatic compressibility (β s E ), excess intermolecular free length (L f E ) and excess molar volume (V E ) respectively in the temperature range 303.15 -323.15 K.…”

Density and ultrasonic velocity have been measured in the binary liquid mixtures of methyl acetate (MA) and ethyl acetate (EA) in 2-methoxyethanol (2ME) over the temperature range from 303.15 to 323.15 K. The measured data are used to compute the excess thermodynamic parameters namely excess adiabatic compressibility (β s E), excess intermolecular free length (L f E) and excess molar volume (V E). A plot of these excess thermodynamic parameters against the mole fraction of methyl acetate and ethyl acetate over the entire composition range shows a negative deviation indicating a strong interaction between the component molecules of liquid mixtures. The results are discussed in terms of formation of hydrogen bonding between the component molecules of the liquid mixtures.

“…Molecular interaction studies in liquid mixtures have significant relevance in many field of applied and theoretical research. Such studies have shown the structure and bonding of associated molecular complex in the binary and ternary mixtures [1][2][3][4][5] . Ultrasonic velocity in a liquid mixture is fundamentally related with the binding forces acting between the atoms or molecules present in the liquid system.…”

; AJC-14489 Density (ρ), viscosity (η) and ultrasonic velocity (U) have been measured for a binary mixture composed of methyl formate and methanol at 303, 308 and 313 K. The adiabatic compressibility (β), acoustic impedance (Z), free length (Lf), free volume (Vf), internal pressure (πi), viscous relaxation time (τ) and Gibbs free energy (∆G) have been calculated from the experimental data. The excess values of these parameters (β E , Z E , Lf E , Vf E , πi E , τ E and ∆G E) have also been calculated by using the determined data and interpreted in terms of molecular interactions. The deviations in the sign and values of these excess parameters from the ideal mixing reveal that intermolecular interactions obtaining in the liquid mixture.
