Abstract: | Density, ultrasonic velocity of pure dioxane (Dx) and ligands, 4,6-dimethyl-7-hydroxycoumarin (L1), 6-ethyl-7-hydroxy-4-methylcoumarin (L2), and 3-chloro-7-hydroxy-4-methylcoumarin (L3) in different percent of Dx-water mixture have been investigated at 303.15 K. Acoustical parameters such as adiabatic compressibility (β), intermolecular free length (L f ), acoustical impedance (Z), relative association (R A ), apparent molar compressibility (Φβ), and apparent molar volume (Φ V ) have also been evaluated from the experimental data of density and ultrasonic velocity. An excellent correlation between a given parameters is observed at all percent of dioxane-water and the result suggests nature of intermolecular interactions between the components. |
