Ultrasonic Studies on Molecular Interactions of N-Phthaloylglycine in Protic and Aprotic Solvents at 303–318 K

Abstract

Ultrasonic studies of (1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)acetic acid (N-phthaloylglycine) in polar and non polar solvent of various concentrations and temperatures 303–318 K are carried out. Ethyl alcohol and DMSO selected as polar and non-polar solvents respectively. Density and ultrasonic velocity measured. Different thermo-acoustical parameters viz. adiabatic compressibility, intermolecular free length, acoustic impedance, surface tension, Rao’s constant, molar volume, wada’s constant calculated with the help of these data using standard formulae. These data are used in understanding the molecular interactions in mixtures.
