ABSTRACT

Consistent vapor liquid equilibria (VLE) were determined for the ternary system isobutyl alcohol (IBA) + isobutyl acetate (IBAc) + N,Ndimethylformamide (DMF) and two constituent binary systems at 101.3 kPa. The IBA+DMF system exhibits negative deviation from ideal behaviour and IBAc +DMF system deviates positively from ideal behaviour. The activity coefficients of the solutions were correlated with its composition by the Wilson, NRTL and UNIQUAC models. The ternary system is well predicted from binary interaction parameters.
