This paper presents the isothermal and isobaric vapor-liquid equilibria measured with an inclined ebulliometer for α-pinene + cis-pinane + 1-hexanol system at temperatures of 368.15K, 383.15 K and 408.15K, and at pressures of 26.66 kPa and 53.33 kPa. The measured ternary results are analyzed using the UNIQUAC equation with the temperature-dependent binary parameters. Satisfactory agreements are obtained between the experimental results and the theoretical analysis.
