 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

Abstract:

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 (?k), specific acoustic impedance (Z) and relative association (RA) 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.

Keywords: Ultrasonic, binary mixture, acoustic, molecular interaction, substituted Schiff bases.
