Description
Summary:New consistent vapor--liquid equilibrium data for the binary systems isobutyl alcohol (IBA)+isobutyl acetate (IBAc) and tert--butyl alcohol (TBA)+tert--butyl acetate (TBAc) are reported at 20 and 101*3kPa. The IBA+IBAc system, which deviates positively from ideal behavior, can be described as symmetric solution and presents azeotrope at both pressures. The TBA+TBAc system shows positive deviations from ideal behavior and presents azeotrope only at 20kPa. The activity coefficients and boiling points of the solutions were correlated with their composition by the Wilson, UNIQUAC, NRTL and Wisniak--Tamir equations.
