摘要：

Isobaric vapor-liquid equilibria data were measured for the 3-methylpentane + ethanol binary system and 2-methyl-2-propanol + ethanol + 3-methylpentane ternary system at 101.3 kPa in a temperature range from 329 to 356 K. The data were found to be thermodynamically consistent according to the Van Ness-Byer-Gibbs method for the binary system and according to the McDermott-Ellis method for the ternary one. The binary system shows a minimum boiling azeotrope that boils at 327.9 K and contains 71.4 mol % 3-methylpentane. The binary interaction parameters obtained from this work and literature data are used to predict the vapor-liquid equilibrium for the ternary system using the UNIQUAC, NRTL, and Wilson models. The ternary system is well predicted from binary data.
