Acoustical Studies of Some Derivatives of 4-Amino Benzoic Acid in 1, 4-Dioxane and Dimethyl Formamide at 308.15 K

Abstract: The ultrasonic velocity, density and viscosity of some Schiff bases of 4-amino benzoic acid were measured in 1,4-dioxane and dimethylformamide at 308.15 K. Various acoustical properties such as isentropic compressibility (s), Rao’s molar sound function (Rm), the Van der Waals constant (b), molar compressibility (W), inter molecular free length (Lf), relaxation strength (r), internal pressure (), solvation number (Sn) etc., were calculated. The results are interpreted in terms of molecular interaction occurring in the solutions.
