Dielectric investigation on a nuclear extractant-acetylacetone (HAA) in nonpolar solvents

Ultrasonic study of binary mixtures of acetylacetone with polar diluents at 303.16 K vis-a-vis molecular interaction

“…Earlier in this study [17] it was of observed that the linear correlation factor g for acetyl acetone is 1.64 indicating predominance of α-multimers with parallel dipolar orientation. The linear correlation factor g is a shape dependent parameter indicative of short-range intermolecular force leading to dipole-dipole interaction.…”

“…Furthermore the nature of variation of g with molefraction of acetylacetone reflects upon the dipolar alignment and hence nature of multimerization of solute molecules. Acetylacetone is an equilibrium mixture of two tautomers [17] the keto and enol forms and there is a possibility of self association in the same liquid in both forms. A wood pile arrangement in both tautomeric forms of acetylacetone [17] does result in parallel alignment and hence α-multimers predominate in pure liquid, whereas antiparallel alignments leads to β-multimers in pure liquids.…”

In enol form, there is internal hydrogen bonding between H δ+ and O δ-in the monomeric species.…”

“…Since the intermolecular interactions under the present investigation are weak type of forces, definite structure of the complex could not be predicted. Acharya et al [17] have studied the interaction of acetylacetone with bromobenzene, chlorobenzene and toluene using dielectric technique.…”

Dielectric Studies of the Ternary Mixtures of Amines With Decanol in Carbon Tetrachloride Systems

“…[1][2] Dielectric data about the mixtures are important due to understanding the nature of intermolecular interactions, hydrogen bonding, solute -solvent etc., [3][4][5][6][7] The molecular interaction occurs due to redistribution of electrons density mainly depends upon following interaction namely electrostatic, polarization and charge transfer.…”
