Ultrasonic velocity, density and viscosity for binary mixtures of Aniline with ethanol, methanol and propanol have been measured at room temperature of about 300.15K over entire volume component percentage range. The ultrasonic velocity (v) is measured with ultrasonic Pulse Echo Overlap (PEO) technique at a frequency of 2 MHz. The density (p) measurements have been carried out by 10 mL specific gravity bottle. The viscosity (η) measurements have been carried out by using Cannon-Fenske Viscometer with an accuracy of ±0.3%. Attenuation coefficient (α), absorptivity (A) was computed using measured data of ultrasonic velocity, density and viscosity. Data of ultrasonic velocity, attenuation coefficient, density and viscosity are useful in evaluating some useful thermodynamic properties like adiabatic compressibility, internal pressure, free volume which can be utilized as a qualitative guide to predict the extent of complex formation in binary liquid mixtures of aniline-alcohol mixtures.
