Ultrasonic speed, u, and density, ρ, have been measured in binary liquid mixtures of cyclohexanone with the isomers of butanol (n-butanol, sec-butanol, and tert-butanol) at 308.15 K over the entire range of composition. Molar volume (Vm), adiabatic compressibility (ks), intermolecular free length (Lf), acoustic impedance (z), and their excess/deviation along with Δu have been calculated from the experimental data. These values have been fitted to Redlich-Kister type polynomial equation. Positive values of VmE, Δks, LfE and negative values of zE, Δu have been observed for all the liquid mixtures indicating the existence of weak interactions between components. Rupture of H-bond or reduction in H-bond strength of isomers of butanol or breaking of the structure of one or both of the components in a solution causes the existence of dispersions in the present investigated binary mixtures. The data obtained from V-m,1, V-m,2, and excess partial molar volumes V-m, 1E, V-m, 2E, reflects the inferences drawn from VmE. Furthermore, FTIR spectra support the conclusions drawn from excess/deviation properties. The measured values of ultrasonic speed for all the investigated mixtures have been compared with the theoretically estimated values using empirical relations such as, Nomoto, Van Dael and Vangeels, Impedance and Rao specific sound speed.

“…This trend supports strong solute-solvent interaction and suggests aggregation of solvent molecules around solute molecules [16][17] . The magnitude of adiabatic compressibility and free length increases with increase in temperature, it clearly reveal that interaction become weaker at higher temperature 18 . The decreases in free length with increase in molar concentration suggest there are good agreements with model of Eyring and Kincaid.…”

ABSTRACT. The nature and the relative strength of the intermolecular interaction between the components of the liquid mixtures have been successfully investigated by ultrasonic method. In present study, the densities (ρ), ultrasonic velocities (u), viscosity(ɳ) and refractive index(n D ) in a ternary liquid mixture of 2-aminothiazole with N,N-dimethylformamide (DMF) in water have been measured at 303.15, 308.15, 313.15,318.15 and 323.15 K respectively, over the entire composition range by using densitometer, ultrasonic interferometer, viscometer and refractmeter respectively. The measured data have been used to compute the various thermo-acoustic parameters using the standard relations namely, adiabatic compressibility (β s ), intermolecular free length (L f ), specific acoustic Impedance (Z),Wada constant (W), molar sound velocity(R), relative association (R A ), apparent molar compressibility(   ),apparent molar volume( V  )viscosity relaxation time(Г), absorption coefficient, internal pressure (ᴨ),free volume (V f ),Gibb ҆ s free energy(∆G) and specific refraction (r), etc. The results have been analyzed on the basis of variation in thermodynamic parameters. These parameters are useful for explaining the molecular association and interaction between the components of ternary liquid mixtures. The variation in densities and ultrasonic velocities with concentrations in the system show similar trends for evaluated parameters of the constituents in ternary mixture at different temperatures. The results have been interpreted in terms of solute-solvent and solvent-solvent interaction.
