Studies in the Acoustic Parameters of 3-Hydroxy-6-Chloro-8-Substituted Flavanol

P. B. Raghuwanshi and A. O. Deshmukh

Ultrasonic velocity and density measurements of 3-hydroxy-6-chloro-8-nitro flavanol (L1) and 3-hydroxy-6-chloro-8-bromo flavanol (L2) were carried out in three different solvents, dioxane, benzene, and ethanol, respectively for investigating solute–solvent and solute–solute interactions. These interactions were also performed at 303 K. The data obtained during the most significant acoustic parameters like, adiabatic compressibility (β), apparent molar compressibility (φk), apparent molar volume (φv), intermolecular free length (Lf) and relative association (RA). These parameters explore solute-solute and solute-solvent interactions in different solvents. In this investigation, the comparative study of effect of solvents and effect of substituents in the solute are studied on molecular interaction of the matter.
