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.Paper presented at the Seventh Asian Thermophysical Properties Conference, August 23–28, 2004, Hefei and Huangshan, Anhui, P. R. China. |
