%X In this work, isobaric vapor–liquid equilibrium
(VLE) measurements
were conducted for the binary systems of water (1) + 2-methyl-propan-1-ol
(2) and 2-methyl-propan-1-ol (1) + pyridine (2) at approximately 50,
80, and 100 kPa using a dynamic equilibrium apparatus. The water (1)
+ 2-methyl-propan-1-ol (2) system was found to be partially miscible
for some intermediate compositions and exhibited azeotropic behavior,
while a maximum boiling azeotrope was observed for the 2-methyl-propan-1-ol
(1) + pyridine (2) system at 51 kPa and approximately x1 = 0.23. Ternary VLE measurements were also conducted
for the water (1) + 2-methyl-propan-1-ol (2) + pyridine (3) system
at 101.3 kPa. The binary VLE data were modeled using the γ–Φ
approach with the Nonrandom Two-Liquid and Universal Quasi-Chemical
activity coefficient models and the virial equation of state. The
measured data were found to be thermodynamically consistent using
the point-type and infinite dilution tests. Ternary VLE data were
predicted from the regressed binary interaction parameters and show
satisfactory comparison to the experimentally determined VLE data.
