Experimental vapor-liquid equilibrium data have been obtained for the system propionic acid-m-xylene at 760 mmHg pressure using a recirculating type equilibrium still. The system formed a minimum boiling azeotrope. The activity coefficients were calculated from experimental data taking into consideration vapor phase imperfection. Nothnagel''s correlation based on chemical theory of vapor imperfection was used to estimate second virial coefficients. The data have been tested for thermodynamic consistency and correlated by Wilson equation as modified by Katayama and Tsuboka.
