“…An increase in the strength of the heteromolecular forces manifests in a decrease in adiabatic compressibility and volume and, hence, the size of the cluster. Thus, the negative V m E values account for the strong interactions between the unlike molecules . Further, Fort and Moore used the positive deviation in viscosity values to account for the presence of strong interactions in binary mixtures.…”

“…Thus, the negative V m E values account for the strong interactions between the unlike molecules. 12 Further, Fort and Moore 13 used the positive deviation in viscosity values to account for the presence of strong interactions in binary mixtures. Thus, the excess molar volume and deviation in viscosity compliments the presence of strong interactions in the mixtures reported in this paper.…”

Densities and viscosities of binary mixtures of toluene with acetone, ethyl methyl ketone, and acetophenone including those of pure liquids are measured over the entire composition range at temperatures (298.15, 303.15, and 308.15) K, respectively, at atmospheric pressure. From these experimental data, the values of excess molar volume V m E and the deviations in viscosity Δη are calculated and fitted to the Redlich−Kister polynomial equation. The variation of these properties shows strong interaction between the molecules of the mixtures.

“…All these ketones are however aprotic molecules having large dipole moment values (2.8 À3.02)D. The polarizability values of ketones are in the order AC < EMK < AP. Further, acetone is known to be extensively self-associated through H-bonding in the pure state [31]. When ketones are mixed with toluene, the strength of interaction between the participating molecules depends on the polarizability and geometry (i.e.…”

“…Carbonyl compounds contain polar group in which electron deficient carbon can function as electrophile. The experimental values of ultrasonic velocities along with densities are used to calculate the values of acoustical parameters such as adiabatic compressibility (κ), free length (Lf), internal pressure (πi), molar volume (Vm) and available volume (Va) [1][2] . The variation of these parameters with different concentrations is used to interpret the intermolecular interactions present among the liquid components.…”

Densities, absolute viscosities and ultrasonic velocities of ternary mixtures of crotonaldehyde and acetone in hexane have been measured for the ternary mixtures at 298.15, 303.15 and 308.15 K in different concentrations under atmospheric pressure. These properties have been used to calculate various thermo-chemical parameters. The variations in these parameters have been studied in terms of nature and extent of interaction. By using the ultrasonic velocity (U), density (ρ) and coefficient of viscosity (η), other acoustical parameters were calculated. The non-linearity in the variation of viscosity is explained in terms of hydrogen bond formation between components of mixtures. The variation in ultrasonic velocity depends on the intermolecular free length on mixing. The value of intermolecular free length increases with increase in temperature and it is maximum at 308.15 K. It shows that weak interaction takes place at higher temperature. The results have been interpreted in terms of specific intermolecular interactions present in the mixtures and are found to support each other.
