Thermodynamic properties of binary liquid mixtures containing 1,3-Dioxolane with alkanols (C5-C10) at 298.15K

Abstract

The excess adiabatic compressibility (β_ad^E), excess molar volume (VmE), acoustic impedance (ZE) and excess viscosity (ηE) have been investigated from sound velocity (u), density (ρ) and viscosity (η) measurements of six binary liquid mixtures of 1, 3-dioxolane with pentanol. Hexanol, heptanol, octanol, nonanol and decanol over the entire range of mole fraction at 298.15K. The excess adiabatic compressibility(β_ad^E) have been calculated from sound velocity measurements of these binary mixtures at 298.15K. The deviation has been fitted by a Redlich-Kister polynomial equation and the results are discussed in terms of molecular interactions. The excess properties are found to be eighter negative or positive depending on the molecular interactions and nature of the liquid mixtures. Excess properties provide important information in understanding the solute-solvent interaction in a solution.
