Densities, Viscosities, and Sound Speed of Binary Mixtures of Hexyl Acetate with Tetrahydrofuran, 1,4-Dioxane, Anisole, and Butyl Vinyl Ether

Abstract

Densities, viscosities, and speeds of sound for the binary mixtures of hexyl acetate with tetrahydrofuran, 1,4-dioxane, anisole, and butyl vinyl ether were measured at (298.15, 303.15, 308.15, and 313.15) K. From the experimental data, values of excess volume, V E, deviation in viscosity Δη, and deviation in isentropic compressibility ΔK S, have been calculated. These results were fitted to Redlich–Kister polynomial equation. The excess volumes V E and deviations in isentropic compressibility ΔK s were found to be completely negative, while the deviations in viscosity Δη were found to be either negative or positive depending on the nature of liquid mixtures.

Structure of anisole derivatives by total neutron and X-ray scattering: Evidences of weak C H⋯O and C H⋯π interactions in the liquid state

“…Anisole density has been reported in a few papers dealing with its mixtures with a variety of compounds. [38][39][40][41] Our MD computed value for this parameter at 298 K is 0.971 g/cc, which is slightly lower than the literature values (ca. Figure 2b) shows that no scattering feature can be detected for Q values lower that first peak position at ca.…”

Application of a General Computer Algorithm Based on the Group-Additivity Method for the Calculation of Two Molecular Descriptors at Both Ends of Dilution: Liquid Viscosity and Activity Coefficient in Water at Infinite Dilution

“…In the present study the viscosity coefficients have been transformed into their decimal logarithm and entered into the group-additivity calculation as log(η). The main sources of experimental viscosity data have been the collective papers of Suzuki et al [5,7] and Katritzky et al [6], supplemented by more recently published experimental results for alkanes [11,12,13,14], haloalkanes [15,16], alkanols [17,18,19,20], alkylamines [21,22,23,24], aminoalcohols [25,26,27], ethers [28,29], aminoethers [30], acetals [31], ketones [32], esters [33,34,35,36,37,38,39,40,41,42,43], hydroxyesters [44,45], carbonate esters [46], and amides [47,48,49,50,51,52]. Beyond these, experimental data have been added for compounds with atom groups that have not yet been represented in the parameters table: phosphoric acid esters [53,54,55], phosphoric acid amides [56], siloxanes [57] and in particular ionic liquids [32,58,59,60,61,62,…”

Density, Speed of Sound, and Refractive Index Measurements for the Binary Mixture (1, 4-Dioxane + Isobutyric Acid) at T = (295.15, 298.15, 301.15, 304.15, 307.15, 310.15, and 313.15) K

“…31 The geometrical contribution is due to the differences in free volumes and molar volumes between the components. 29 The chemical interactions contribute negatively to the excess molar volume. 32,33 The factors that causes expansion of volume on mixing of the components can be explained in the terms of dissociation of one component or both of the components, steric hindrance due to branching of chains, geometrical mismatch of molecules, and formation of weaker solute−solvent bond than solute− solute and solvent−solvent bonds, solvent−solvent bonds.…”

“…27,28 The factors that cause contraction on mixing can be analyzed qualitatively in terms of strong specific interaction, usually a kind of chemical interaction, strong physical interaction and geometrical contributions. 28,29 The physical interactions comprise mainly dispersion forces giving a positive contribution 30 such as dipole−dipole or dipole−induced dipole interaction between the mixing components. 31 The geometrical contribution is due to the differences in free volumes and molar volumes between the components.…”

“…The determination and prediction of excess thermodynamic properties of liquid mixtures have a great interest for the convenient design of industrial processes like distillation and fluid phase separation. 1 Moreover, they provide useful information on molecular interactions required for optimizing thermodynamic model development as well as their applications in some branches of science. Considerable progress has been made in the theoretical understanding of liquid−liquid mixtures.…”
