Vapor–liquid equilibrium at 0.15 MPa for binary mixtures of butyl acetate with methanol, ethanol, 1-propanol, and 1-butanol has been measured. The thermodynamic consistency was verified with the Redlich–Kister test, the Herington test, the direct Van Ness test, and the point-to-point test. Azeotropic data was found for the butyl acetate + 1-butanol binary system at 0.15 MPa. Modeling of binary systems was obtained by employing the group contribution models (ASOG and different versions of UNIFAC) and the perturbed chain-statistical associating fluid theory equation of state.
