“…Studies reported the ΔR of binary mixtures based on volume fraction 14,15,31,[46][47][48]62,68,69 and mole fraction basis. 9,52,65,70 It is implied that there is no general rule that states how to interpret molar refractivity function. 68,69 In addition, as reported by Konti et al, the deviation in molar refractivity with volume fraction is based on the Lorentz−Lorentz mixing rules.…”

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 negative values viscosity deviation indicates that the dispersion forces are dominant. [16][17][18] The viscosity deviation (∆ŋ) values indicate that there is a survival of dispersion and dipolar forces between dissimilar molecules and associated with the variation in shape and size of the dissimilar molecules. The obtained values suggest that the existence of intermolecular force upon mixing of three binary liquid mixtures.…”

In this article, the behavior of carbon tetrachloride + 2-methoxyethanol, carbon tetrachloride + 2-ethoxyethanol and carbon tetrachloride + 2-butoxyethanol are studied. Density and Viscosity of above three binary mixtures have been measured, studied as a function of temperature and composition. Molar volume, Viscosity deviations and Excess Gibb's free energy of activation of flow have been calculated. Excess properties are fit to the Redlich-Kister model to obtain the coefficients and standard error. The results of three binary liquid mixtures signify a strong specific type of interaction between the unlike molecules.

“…Vogel and Weiss 23 clarified that mixtures with solid communications between various molecules and negative deviations from Raoult's law display positive viscosity deviations while for mixtures with positive deviations of Raoult's law and without particular connections, the viscosity deviations are negative. 24 , which recommends that the position of -CH 3 groups on the aromatic ring assumes a generous part in choosing the extent ∆η and thus, the order of collaboration between the component molecules of the mixtures. The stereo normality of methyl groups in o-xylene is such that the steric repulsion is more.…”

Densities and viscosities of binary liquid mixtures of diethyl malonate with isomeric xylenes were reported at different temperature. From the experimental data, deviation in viscosity (∆η) and excess Gibbs free energy of activation of viscous flow (∆G *E) were assessed. The deviations in viscosity and excess Gibbs free energy of activation of viscous flow were correlated with Redlich-Kister polynomial equation. Viscosity theories like Grunberg-Nissan, Katti-Chaudhri, Heric-Brewer, Hind et al., and McAllister four body models have been applied to correlate the viscosity of binary mixtures.
