Isobaric Vapor-Liquid Equilibria for the System Containing Acetic acid at 101.3kPa

摘要

Isobaric vapor-liquid equilibria (VLE) data for water + acetic acid, acetic acid + K-pentyl acetate, water + acetic acid + n-pentyl acetate systems have been measured at 101.33 k Pa 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'Connellmethod. 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.
