We present experimental data of speed of sound (u), viscosities (η) and densities (ρ) for the binary liquid mixtures of cyclic diether with 1-alknols at 298.15 K by using ultrasonic interferometer technique. From the experimental values of speed of sound (u), viscosities (η) and densities (ρ) have been used for study of the molecular interaction in the different liquid mixtures using the excess values of parameters such as excess surface tension (SE), excess available & B i o volume (VaE), excess relaxation strength (rE), excess enthalpy (HE) and excess free volume (VfE) variation in the above parameters for the different liquid mixtures is indicative of the nature of molecular interaction between them. For all studied systems, excess surface tension (SE), excess available volume (VaE), excess relaxation strength (rE), excess enthalpy (HE) and excess free volume (VfE) were negative over the entire mole fraction range of 1,3-dioxolane at measured temperatures. The obtained results are interpreted in term of intermolecular interaction in binary liquid mixtures.
