Abstract
Isobaric vapor-liquid equilibrium (VLE) data have been determined at (53.3 and 91.3) kPa for the binary
mixtures of heptane + 1-butanol and heptane + 1-pentanol. The VLE data of binary systems were found
to be thermodynamically consistent. In addition, the experimental VLE data were correlated by using the
Wilson, nonrandom two-liquid (NRTL), and universal quasi-chemical (UNIQUAC) activity coefficient models
for the liquid phases. The binary interaction parameters of the activity coefficient models have been determined
and reported. A comparison of model performances has been made by using the criterion of the average
absolute deviation (AAD) in boiling-point and vapor-phase composition. The obtained results indicate that
the used activity coefficient models satisfactorily correlate the VLE data of the studied systems
