Abstract: Sound velocity, density and viscosity have been measured in the ternary mixtures of 1-butanol in pyridine with benzene at 303K. Some of the acoustical parameters such as adiabatic compressibility, free length, free volume and internal pressure are calculated from the measured data using the standard relations. The trend shown by the excess parameters of free volume and internal pressure is peculiar that both are negative and in increasing order confirms that the associative nature of alcohol disturbs the molecular symmetry available in benzene molecule. The reduction in the cohesion of dipolar pyridine is also noticed.
