Temperature dependence of adiabatic compressibilities of and sound velocities in p-dioxane–water mixtures

Abstract

The effect of p-dioxane on the temperature of adiabatic compressibility minimum (TACM) and sound velocity maximum (TSVM) in water have been studied. Both the structural shifts, [ΔTβ str]exp and [ΔTu str]exp, are found to be positive, increasing with concentration and reaching maximum values around [Formula: see text] These results have been explained as due to the formation of hydrates of dioxane of varying composition indicating the existence of long range order in the water + p-dioxane System in the water-rich region.
