Dielectric data of binary mixtures of Isoamyl alcohol with 2-butanone at T= 298.2 K

Studies of the dielectric and thermodynamic properties of binary mixtures including alcohols are important and desirable in deep understanding the nature of intermolecular interactions and consequence structure in the mixture due to the hydrogen bonding and other electrostatic interactions [1]. The heterogeneous and homogeneous interactions in binary mixtures using dielectric measurements have been studied and reported by several investigators [2]. Ketones are carbonyl-containing compounds that have a large range of applications in various industries. They are used as solvents or chemicals in the manufacture of gums, wax, glues, paraffin, resins, textile, and plastic [3]. These organic compounds belong to dipolar aprotic solvent groups, which are well hydrogen-bond acceptors.This paper reports the role of hydrogen bonding and other electrostatic interactions on the dielectric behaviour, excess parameters, and structure properties of the binary system (Isoamyl alcohol + 2-butanone).Relative permittivity measurements were made on binary mixtures of (Isoamyl alcohol + 2-butanone) for various concentrations at T = 298.2 K. In order to obtain valuable information about heterogeneous interaction (interactions between the unlike molecules), the Kirkwood correlation factor, the Bruggeman dielectric factor and the excess permittivity were calculated.
