Ultrasonic studies of N-(2-hydroxybenzylidene)-3-substituted pyridine-2-amine Schiff bases in binary mixture of 1, 4-dioxane-water at 293, 297 and 300 K

Ultrasonic velocity and density of N-(2-hydroxybenzylidene)-3-substituted pyridine-2-amine Schiff bases have been measured in binary mixture of dioxane-water at 293, 297 and 300 K. From the experimental recordings, various acoustic parameters like apparent molar compressibility (Φk), specific acoustic impedance (Z) and relative association (R_A) have been evaluated for dioxane-water system of different concentrations. It helps in understanding the molecular interactions occurring inbetween water molecules and organic solvent molecules with substituted Schiff bases.
