چکیده انگلیسی
The present study describes interactions between aniline + benzene, + toluene, + o-xylene, and + p-xylene mixtures at 298.15 K. The experimental values of refractive indices (nD) and dielectric constants (â) of pure aniline, benzene, toluene, o-xylene and p-xylene and their binary mixtures over the whole composition range at 298.15 K have been obtained. Using these experimental data, the values of deviations in dielectric properties (âE), refractive indices (nD2E), molar polarization (PE) of aromatic hydrocarbons in aniline have also been calculated and apparent molar polarization (PA), equilibrium constant (K), apparent dipole moment (µapp) and Kirkwood correlation parameter (g) for these mixtures have been evaluated further. The results indicate specific interactions between aniline and aromatic hydrocarbons, although more than one competing factors are responsible for these observed values of excess properties. The internal consistency of these functions have been tested using Redlich-Kister type equation.
