“…In general, u and L f vary in a reciprocal manner with the mole fraction, x 1 , of a mixture [43,44]. A perusal of Table 2 reveals that the values of u decrease with an increase in x 1 of halohydrocarbons for all the binary mixtures under consideration (Fig.…”

Densities, ρ, and ultrasonic speeds, u, of binary mixtures of hexan-1-ol with 1,2-dichloroethane, 1,2-dibromoethane, and 1,1,2,2-tetrachloroethene have been measured over the entire range of composition at (293.15 and 298.15) K and atmospheric pressure. From these data, the excess molar volumes, V E , deviations of ultrasonic speed, u D , from the ultrasonic speed of an ideal mixture, excess molar isentropic compressibilities, κ E S,m , intermolecular free lengths, L f , mean molecular radii, r , and thermal expansion coefficients, α, have been calculated. The experimental ultrasonic speeds have been analyzed in terms of Nomoto's, Van Dael's ideal mixture, and Junjie relations; Jacobson's free length and Schaaffs' collision factor theories; and thermoacoustical parameters.

“…The weighings were done on a Preisa XB 220A (Swiss make) electronic balance with a precision of ±0.0001 g. The probable uncertainty in the mole fraction, x, was estimated to be <0.0001. The densities of the pure liquids and their mixtures were measured by a single capillary pycnometer as described in our earlier papers [1][2][3][4][5]. The pycnometer was calibrated with triple-distilled water at 298.15 K, 303.15 K, 308.15 K, and 313.15 K. The measured densities were accurate to 0.0001 g · cm −3 .…”

The densities, ρ, viscosities, η, ultrasonic speeds, u, and refractive indices, n D , of pure benzene, methyl acrylate (MA), ethyl acrylate (EA), butyl acrylate (BA), styrene (STY), and their binary liquid mixtures have been measured over the entire composition range at 298.15 K, 303.15 K, 308.15 K, and 313.15 K. The experimental data have been used to calculate excess molar volumes. Partial molar volumes of MA/EA/BA/STY in benzene at infinite dilution and at different temperatures have also been evaluated. The results were discussed in terms of molecular interactions prevailing in the mixtures.

“…Derived parameters such as internal pressure and free volume studies will be useful to know the molecular interactions of the systems. Ultrasonic velocity measurements have been successfully employed to detect and assess weak and strong molecular interactions in binary liquid mixtures [5][6] . In this paper an attempt is made to investigate the ultrasonic studies of binary mixture systems of ethylmethylketone (EMK) and N, N-dimethylformamide (DMF) at 298, 308and 318.…”

Ultrasonic velocities (u), densities () and viscosities () are measured in respect of ethylmethylketone (EMK) and N,N-dimethylformamide (DMF) over the entire composition at 298, 308and 318K. Attempt have been made to extract the information with respect to various kind of intermolecular interactions, such as H-bonding, dipole-dipole, solute -solvent, dispersion type interactions existing between these two components from the following acoustical parameter when examined as a function of solvent composition at different temperatures: adiabatic compressibility (), specific acoustic impedance (Z), intermolecular free length (L f ), molar sound velocity (R m ), wada's constant (W), viscous relaxation time (), free volume and internal pressure ( i ).
