Theoretical Evaluation of Ultrasonic Velocities in Quanternary Systems

Abstract

Ultrasonic velocity and densities of quaternary systems:
chloroform-1,4-dioxane-toluene-cyclohexanone. chloroform-1,4-
dioxane-toluene-hexane and chloroform-1,4-dioxane-toluene-heptane
have been measured at 298 K as a function of concentration
and these experimental values are compared with theoretical values
evaluated by using various theories such as Flory  Auerback,
Nomoto, Van Deal-Vangeal, Rao's specific velocity, collision factor
and impedance dependence. The relative applicability of these
theories to the present systems has been checked and the results are
explained in terms of molecular interactions occurring in these systems.
