摘要 Investigating phase equilibrium on the terpenoid of the pineoleoresin system is of great importance for the usage relevant to the oleoresin.Herein, the binary and ternary isothermal vapor-liquid equilibrium (VLE) of alpha-pinene, longifolene, and abietic acid (three main components of oleoresin) at313.15, 323.15, and 333.15 K were measured by headspace gas chromatography(HS-GC). There was no azeotropic behavior observed of alpha-pinene andlongifolene. Abietic acid'sinfluence on separating alpha-pinene and longifolene wasdiscussed. The relative volatilities of alpha-pinene and longifolene decrease in thepresence of abietic acid, indicating a negative impact of abietic acid on theirseparation. The experimental data were correlated well with the nonrandomtwo-liquid, universal quasichemical, and Wilson models. The binary interaction parameters for each equation were also obtained, andthe largest mean relative deviation of vapor-phase mole fraction and the largest absolute average deviation of pressure are 0.1975%and 0.0856 kPa, respectively.
