Viscometric and ultrasonic investigation of solute-solvent interaction of hexadecylamine based Schiff's base in ethanol at 303.15 K

The ultrasonic velocity, density and viscosity of salicylaldehyde (SA), hex adecylamine (HDA), 1:1 mixture (of SA& HDA) and Schiff's base (synthesized from SA & HDA) in ethanol at 303.15 K have been measured. The ultrasonic ve locity data are used to estimate various acoustic parameters such as isentr opic compressibility, intermolecular free length, acoustic impedance, molar sound velocity and molar compressibility. These parameters along with the B-coefficient as calculated from Jones-Dole equation provide information ab out the type of interaction taking place in these systems. The ultrasonic v elocity data of salicylaldehyde + ethanol have been analyzed in terms of No moto and ideal mixing relations. (C) 1999 Elsevier Science B.V. All rights reserved.
