Isobaric vapor-liquid equilibria (VLE) were measured for the ternary system 1-pentanol + nonane + anisole and for two constituent binaries, nonane + anisole and 1-pentanol + anisole, at the pressures (26.66, 53.33, 79.99, and 101.32) kPa. Boiling temperature (T)-liquid composition (x) relations were obtained by using a semimicroebulliometer. A minimum boiling azeotrope was observed in nonane + anisole and in 1-pentanol + anisole. The azeotrope in the ternary system was observed only at the pressure 26.66 kPa. The Wilson equation was used to correlate the binary T-x data and to predict VLE in the ternary system.
