Ultrasonic velocity (v), density (ρ) and viscosity (η) of binary liquid mixtures of ethyl acetate and 1-alkanols has been measured using ultrasonic interferometer, 30 ml gravity bottle, pycnometer and ubblehode viscometer respectively at frequency 3 MHz and constant temperature 303.15 K. The ultrasonic related like parameters sound velocity (v), density (ρ) and viscosity (η) and computed values of deviation in viscosity (Δη), molar volume (V), excess molar volume (VE), adiabatic compressibility (βad), deviation in adiabatic compressibility (Δβad), intermolecular free length (Lf), excess intermolecular free length (Lf E), acoustic impedance (Z), excess acoustic impedance (ZE), Rao's Constant (R), Wada constant (W), viscous relaxation time (t) and relaxation strength (r), were determined. Graphs are plotted of each parameter against mole fraction (x1). The obtained result support the occurrence of molecular association through hydrogen bonding in the binary liquid mixtures.

The wide use of 1, 4-dioxane (cyclic ether) as a degreasing agent, as a component of paint and varnish removers and as a wetting and dispersion agent in the textile industry. In the present study ultrasonic velocity (u), density (ρ) and viscosity (η) of 1, 4-dioxane with alkanols systems have been measured experimentally at 303.15 K over the frequency 3 M. Hz. using ultrasonic interferometer technique. The measured values of ultrasonic velocity (u), density (ρ) and viscosity (η) have been used to estimate the acoustical parameters namely adiabatic compressibility, (βad) free length (Lƒ), acoustic impedance (Z), relaxation strength (r), molar compressibility or Wada constant (W), Rao's constant (R), Molar Volume (Vm), relaxation time (τ) and internal pressure (pi) with a view to investigate the nature and strength of molecular interactions. The obtained result support the occurrence of molecular association through hydrogen bonding in the binary liquid mixtures.Keywords

The ultrasonic velocity of liquids and liquid mixtures play very important role in understanding the nature of molecular interaction occurring in the system. This paper presents experimental data for density (ρ), ultrasonic velocities (u)and viscosity values (η)of pure ethyl acetate, methanol, ethanol, propanol, butanol, hexanol, octanol and their binary mixtures with ethyl acetate as a common component over the whole composition range at 303.15 K. From these data acoustical parameters such as adiabatic compressibility, free volume, molar volume, available volume and their excess values are evaluated. From the properties of these acoustical parameters, the nature and strength of molecular interactions in these binary systems are discussed. The non-linear variation of these parameters shows the presence of interaction and their excess values is indicative of interaction between the components molecule in all systems.Keywords
