| Abstract: | The separation
efficiency of aniline by destructing the azeotropic formation in the binary
toluene + iso-butanol has been
analysed using ultrasonic techniques. Ultrasonic velocity, density and
viscosity values have been measured at 303 K in the ternary system of aniline +
toluene + iso-butanol and thermo
dynamical approach is applied to evaluate the molar volume, adiabatic
compressibility, internal pressure, molar cohesive energy and their excess
values. Results are interpreted in terms of molecular interactions between the
components of the mixtures and compared with molecular interaction parameter
that can highlight the role of aniline in the azeotropic destruction of the
chosen binary. Observed excess values lend further support to the interactions
found in the binary and ternary systems. The dipole type interaction existing
between aniline and iso-butanol is found to be the predominant factor for
destructing the azeotrope formation. |
