New experimental data were measured for phase transition of the binary system CO2 + black sesame oil. A variable volume cell was employed using the static synthetic method in a temperature range of 303-333 K, pressures up to 20 MPa, and CO2 mass fractions between 0.12-0.39 g/g. For mass fractions > 0.39, phase transition data were not measured due to pressure limitations of the high-pressure system used. Vapour-liquid transitions (VLE) of bubble point (BP) were determined. Phase transition data of CO2 + black sesame oil were compared to reported data from the literature involving CO2 and similar oils. The trend of the phase transition behaviour between all systems compared was similar. Phase equilibrium data obtained experimentally were successfully modelled with the Peng-Robinson equation of state (PR-EoS) combined with the van der Waals mixing rule (PR-vdW2) and Wong-Sandler mixing rule (PR-WS).
