Abstract

Density, viscosity and sound velocity of six binary liquid mixtures of methanol, ethanol, propanol, butanol, hexanol and octanol with 1,4-dioxane have been measured over the entire range of composition at temperature 303.15K. From the experimental densities, viscosities and sound velocity, the excess molar volume (VE), deviation in viscosity (Δη) and deviation in isentropic compressibility (ΔKS) have been calculated. The results have been used to discuss the nature and strength of intermolecular interactions in these mixtures.

Highlights

  • The present paper is part of our ongoing research on the thermodynamic properties of binary liquid mixtures [1] containing 1,4-dioxane with 1-alkanol at 303.15 K

  • Viscosity and sound velocity of six binary liquid mixtures of methanol, ethanol, propanol, butanol, hexanol and octanol with 1,4-dioxane have been measured over the entire range of composition at temperature 303.15K

  • A wide range of important binary mixtures containing the above liquids have been studied by different authors [7] [8] [9] [10]

Summary

Introduction

The present paper is part of our ongoing research on the thermodynamic properties of binary liquid mixtures [1] containing 1,4-dioxane with 1-alkanol at 303.15 K Their binary mixture properties are needed as a useful database in a variety of industrial applications [2] [3] [4] [5] [6]. Their interactions with different types of liquids such as 1,4-dioxane, methanol, ethanol, propanol, butanol, hexanol and octanol are important from a fundamental viewpoint.
