Isobaric vapor-liquid equilibrium data at a local atmospheric pressure of 96.5 kPa is reported for the four binary systems, namely, 2-methyl propan-2-ol (1) + heptan-1-ol (2), methanol (1) + heptan-1-ol (2), ethanol (1) + heptan-1-ol (2), and propan-1-ol (1) + heptan-1-ol (2). The experiments are done using a Swietos.awski-type ebulliometer. The liquid-phase activity coefficients are mcdeled using the well-established Wilson model and the universal functional (UNIFAC) group contribution method. The data are found to be thermodynamically consistent.
