Effective Average Correlation Factor and Excess Permittivity for Dielectric Studies on Binary Systems of Phthalates with Alcohols and Nitriles

Abstract

The determination of the structure and properties of associated liquids could provide deeper insight into the phenomenon of the molecular interactions and is of great importance in biology and chemical physics. Dielectric constant measurements have been extensively used to obtain the electric dipole moment of molecules with the object of determining the polarities of their bonds, geometrical structures of the molecules and significant shifts of the electric charge in them. Dielectric parameters such as Kirkwood correlation factor, effective correlation factor, corrective correlation factor and thermo dynamical excess parameters for a mixture of diethyl phthalate with isobutanol and benzonitrile were determined at 303 k, 313 k and 323 k. The results were interpreted accordingly.
