Effect of lower to higher alkyl chain length cation (R4N+) of quaternary alkyl ammonium iodide salts and dielectric constant (ε) on thermo-physical properties in the homogeneous system of the ternary liquid mixtures of 1, 4-dioxane + dimethyl sulfoxide (DMSO) + water as well as the constituent binaries have been measured at 303.15 K, 313.15 K and 323.15K. The respective acoustical parameters were correlated as a function of the % composition using empirical and thermodynamic based relations. The data obtained from ultrasonic propagation parameters with variation in the % composition as well as dielectric constant (ε) of one of the component of the medium are provide a deep and meaningful picture of various interactions taking place in ternary and higher component liquid mixtures in terms of physical parameters. The reason for this study at different temperatures is that weak and strong complex formation that arises in hydrogen bonds. The present investigation has been under taken to study the nature of molecular interactions, molecular rearrangement and hydrogen making/breaking phenomena takes place.

The data obtained from ultrasonic propagation parameters with variation in the % composition as well as dielectric constant (ε) of one of the component of the medium are provide a deep and meaningful picture of various interactions taking place in ternary and higher component liquid mixtures in terms of physical parameters.
