The ultrasonic velocity (U) density (ρ) and viscosity (η) of binary liquid mixture of Ammonium Hydroxide with ethanol have been measured over the entire range of compositions at the temperature 313K and frequency 1MHz. The observed basic experimental data have been utilized to evaluate some of the derived thermo acoustic parameters such as free volume, internal pressure, relaxation time and Gibbs free energy. The behavior of these parameters and the excess values of free volume, Internal pressure, relaxation time, and Gibbs free energy were evaluated with composition of the mixture and have been discussed in terms of nature and strength of molecular interactions between the constituents.Keywords

Ultrasonic velocity and absorption measurement provides qualitative information regarding the nature and strength of interaction in the liquid mixtures. These studies are important because of their extensive use in the engineering, process industries, textile industries, pharmaceutical industries, nuclear energy industries. A growing specialty application for acrylonitrile is in the manufacture of carbon fibers. These are produced by pyrolysis of oriented poly acrylonitrile fibers and are used to reinforce composites for high-performance applications in the aircraft, defense and aerospace industries. Present paper reports the ultrasonic velocity (u), absorption (α), density (ρ), and viscosity (η), which has been measured at different frequencies (1 MHz to 10 MHz) in the binary mixtures of methanol with acrylonitrile over the entire range of composition at temperature 303 K. Van der Waal’s constant (b), adiabatic compressibility (β), acoustic impedance (Z), molar volume (V), relaxation time (τ), Wada constant (W), free length (Lf), isothermal compressibility (βi), etc have been calculated. The result has been used to discuss the nature and strength of molecular intermolecular interactions in the system. These variations depend on structural changes due to intermolecular interactions in short regions around the molecules.Keywords

The molecular interaction studies in the binary liquid mixtures of two aliphatic alcohols with 1, 4-dioxane has been carried out at 308 K using ultrasonic technique. The ultrasonic velocity, density and viscosity at 308 K have been measured in the binary systems of 1, 4-dioxane and ethanol with methanol. From the experimental data, various acoustical parameters such as adiabatic compressibility (βa), intermolecular free length (Lf), free volume (Vf) and internal pressure (Πi) were calculated. It has been observed that, weak dispersive type intermolecular interactions are confirmed in the systems investigated. Dipole inducement is found to be more predominant in methanol system. The results are interpreted in terms of molecular interaction between the components of the mixtures.Keywords

The ultrasonic velocity density and viscosity of binary liquid mixture of tetrahydrofuran and strontium hydroxide (solvent) have been measured over the entire range of compositions at the temperatures 298K, 303K, 308K at fixed and frequency 7 MHz. The observed basic experimental data have been utilized to evaluate some of the derived thermoacoustic parameters such as adiabatic compressibility, molar volume relaxation time. The behavior of these derived parameters and their excess values of, adiabatic compressibility, molar volume relaxation time were evaluated with composition of the mixture and have been discussed in terms of nature and strength of molecular interactions between the constituents. Broad classification study also helps to understand the molecular interaction types.Keywords
