The vapor–liquid equilibrium data of the three binary systems, including components cumene, t-butylbenzene, and sec-butylbenzene, were determined at 101.3 kPa in this paper. systems did not exhibit azeotropic behavior under experimental conditions. Fredenslund test, Redlich–Kister area Wisniak's L-W test checked thermodynamic consistency data. correlated by nonrandom two-liquid, Wilson, universal quasi-chemical activity coefficient models, their respective interaction parameters obtained correspondingly. maximum absolute deviation, root-mean-square average deviation between computed values models calculated as well. It showed that all could fit This study can help designing distillation process industrial applications.
