Abstract:
The experimental density and speed of ultrasound measurements have been measured for pure Ethylbenzene (ETB), p-xylene and their binary mixtures over the whole miscibility range at different temperatures 293, 298, 303, 308 and 313 K. These parameters were used to determine the adiabatic compressibility, intermolecular free length, acoustic impedance and their excess values. The variation of these parameters with composition of mixture indicates the nature and extent of interaction between unlike molecules. The non-ideal behavior of the system studied was explained on the basis of the dipole-induced dipole interactions and hydrogen bonding. The binary data of βE, ZE and 𝐿fE were correlated as a function of mole fraction by using the Redlich-Kister equation.
