Abstract
Experimental values of ultrasonic velocity (u), density (ρ) and viscosity (η) for the binary mixtures of ethyl acetate with 1-alkanols have been measured at 303.15 K over the entire mole fraction range. Using these data, the excess isentropic compressibility (βEs), excess intermolecular free length (LEf), excess molar volume (VEm), excess free volume (VEf) and excess available volume (VEa) have been calculated. These parameters were used to study the nature and extent of intermolecular interaction between component molecules present in the binary mixtures. Excess values of isentropic compressibility, intermolecular free length, molar volume, free volume and available volume were plotted against the mole fraction of ethyl acetate over the whole composition range. From the properties of these excess parameters, the nature and strength of the interactions in these binary systems are discussed.
Keywords: Acoustical parameters, ultrasonic velocity, density, binary mixtures, ethyl acetate, 1-alkanols.
