Abstract
Isobaric vapor−liquid equilibria (VLE) data for water + acetic acid, acetic acid + isopropyl acetate, acetic acid + n-pentyl acetate, water + acetic acid + isopropyl acetate, and water + acetic acid + n-pentyl acetate systems have been measured at 101.33 kPa using a recirculating still. The nonideality of the vapor phase caused by the association of the acetic acid has been corrected by the Hayden−O'Connell method. The three experimental binary data have been correlated by the NRTL and UNIQUAC models. The obtained NRTL model parameters from binary data have been used to predict ternary VLE data. The ternary predicted values obtained in this way agree well with the experimental values.
