Ultrasonic studies of some derivatives of 6-ethylbenzene-1,3-diol in 1,4-dioxane

Abstract

Ultrasonic velocity, density and viscosity of solutions of some derivatives of 6-ethylbenzene-1,3-diol in 1,4-dioxane were measured at 308.15 K. From these experimental data, various acoustical properties such as specific impedance ( Z), isentropic compressibility ( κ s), Rao’s molar sound function ( R m), the van der Waals constant ( b), molar compressibility ( W), intermolecular free length ( L f), relaxation strength ( r), relative association ( R A), free volume ( V f), etc. were calculated. The results are interpreted in terms of molecular interactions occurring in the solutions.
