Isothermal vapor–liquid equilibrium (VLE) data for expensive and thermosensitive Litsea cubeba oil systems, citral + linalool, citral + α-pinene, and linalool + α-pinene, were measured at 333.15, 368.15, and 403.15 K using headspace gas chromatography, respectively. The Wilson, nonrandom two-liquid (NRTL), and universal quasi-chemical equation (UNIQUAC) models were employed for VLE data regression, and the results showed a good agreement. The maximum absolute average deviation (AAD) of vapor compositions for all systems at the measured temperatures using the Wilson model, NRTL model, and UNIQUAC model was 0.61, 0.49, and 0.50%, respectively, and the maximum mean relative deviation (MRD) for these three models was −2.83, −2.59, and −2.53%, respectively. In addition, the excess Gibbs energy (G^E) for all systems was calculated using the Wilson model.
