【Abstract】 Two sets of vapor—liquid equilibrium data for binary system ethylbenzene (1)—isopropylbenzene (2) were measured at 98.66 kPa and 53.33 kPa. Then they were correlated with Wilson and NRTL activity coefficient equations. The best matching parameters of the equations were obtained from the vapor—liquid equilibrium data. Using the best parameters obtained, the vapor phase compositions and boiling points of binary systems were predicted. The comparison of the predicted values with the data measured is satisfactory. The two sets of data have been tested with the point test method and they have passed the thermodynamic consistency test.更多还原
