Investigation of Molecular Interaction in Binary Liquid Mixtures of some Cyclic Ether with N-Alkanols at 298.15K: By Ultrasonic Velocity Measurements

In the present study, we reported the densities and excess molar volumes and (V_m^E) excess acoustical impedance (ZE) for the pure organic solvent mixtures such as 1,3-Dioxolane + Pentanol, 1,3-Dioxolane + Hexanol, 1,3-Dioxolane + Heptanol, 1,3-Dioxolane + Octanol, 1,3-Dioxolane + Nonanol and 1,3-Dioxolane + Decanol at 298.15K. Excess molar volumes (V_m^E) excess acousticimpedance (ZE) for these binary mixtures were calculated from the experimental density and sound velocity data and fitted to the Redlich-Kister polynomial equation to check the accuracy of experimental data. In addition, the interactions between the unlike molecules in the mixtures were confirmed by using the experimental results. It has been observed that, weak dispersive type intermolecular interactions are confirmed in the systems investigated. Dipole inducement is found to be more predominant in the system. The results are interpreted in terms of molecular interaction between the components of the mixture.
