Studies on molar volume, dielectric properties and refractive indices of Cyanex 923Â +Â benzene/xylene at 300Â K

The present investigation describes interactions between Cyanex 923 and benzene/xylene at 300 K. The experimental values of molar volume, dielectric constant, refractive index, molar polarisation and molar refraction of pure Cyanex 923, benzene and xylene and their binary mixture over the entire mole fraction range have been determined. The excess parameters, Kirkwood correlation parameter, Gibb's free energy of mixing for these binary mixtures have been evaluated. The excess parameters have been tested using Redlich-Kister equation. The results indicate very weak interactions between Cyanex 923 and benzene/xylene.
