Study of molecular interaction between some primary alcohols and anilines using concentration dependent dielectric properties

Abstract

The static dielectric constant (ε₀) and optical dielectric constant (ε­_∞ = <i style="mso-bidi-font-style:normal">n</i>²) of binary mixtures of some lower order primary alcohols with aniline, 2-fluoroaniline and 4-fluoroaniline over the concentration range (0.0, 0.1, …. 1.0) by volume fractions are measured at fix frequency 2 MHz using precision LCR meter and Abbe’s refractometer, respectively. The excess dielectric constant, Kirkwood correlation parameter and Bruggeman parameter have been evaluated. The variations of these parameters with composition indicate the presence of molecular interaction between the participating components in these mixtures.
