ABSTRACT
Isobaric vapor liquid equilibrium data were obtained for 1-butanol p-xylene system at 97.3 kPa using a vapor recirculating type (modified Othmer s) equilibrium still. The activity coefficients were obtained by taking into consideration vapor-phase imperfections. The experimental data for this system were tested for thermodynamic consistency and were correlated by various equations. The system forms a minimum boiling azeotrope.
