Abstract

Experimental determined density, viscosity and sound velocity for binary mixtures of 1,3-dioxolane + 1-alkanols at T= 298.15 K, are conducted at atmospheric pressure. From these experimental values, various thermodynamic and excess thermodynamic properties were calculated. The adiabatic compressibility (βad), excess adiabatic compressibility (βadE), inter molecular free length (Lf), excess inter molecular free length (LfE), enthalpy (H), excess enthalpy (HE), free volume (Vf), excess free volume (VfE), internal pressure (Pi), excess internal pressure (piE) have been investigated from density (ρ), viscosity (η) and sound velocity (u) measurements of six binary liquid mixtures of 1,3-Dioxolane with pentanol, hexanol, heptanol, octanol, nonanol and decanol over the entire composition range of mole fractions at 298.15K. An excess value of adiabatic compressibility (βadE), inter molecular free length (LfE), excess enthalpy (HE), excess free volume (VfE) and excess internal pressure (piE) were plotted against the mole fraction of 1,3-dioxolane over the whole composition range. The values of (βadE), (LfE), (HE), (VfE) and (piE) for six binary liquid mixtures have been found to be negative which suggest the presence of weak molecular interaction in all the six binary mixtures. These mixtures exhibit very strong cross association through hydrogen bonding.
