The present work deals with the study of acoustic parameters like ultrasonic velocity (V), adiabatic compressibility (β s ), apparent molar volume ( f v ) and intermolecular free length (L f ) by ultrasonic interferometric measurements which reflects structural interaction of water molecules and organic solvent molecules with substituted Schiff bases. The study of N–(2-hydroxybenzylidene)-3-substituted pyridine -2- amine Schiff bases were carried in different percentage of 1,4-dioxane-water medium, at 293, 297 and 300 K. The densities and velocities thus obtained were used to evaluate acoustic parameters for all the ligands.
