| 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. |
