摘要：
The solubility of red palm oil(RPO) in supercritical carbon dioxide(scCO) was determined using a dynamic method at 8.5–25 MPa and, 313.15–333.15 K and at a fixed scCOflow rate of 2.9 g·minusing a full factorial design. The solubility was determined under low pressures and temperatures as a preliminary study for RPO particle formation using scCO. The solubility of RPO was 0.5–11.3 mg·(g CO)and was significantly affected by the pressure and temperature. RPO solubility increased with pressure and decreased with temperature. The Adachi–Lu model showed the best-fit for RPO solubility data with an average relative deviation of 14% with a high coefficient of determination, R~2 of 0.9667, whereas the Peng–Robinson equation of state thermodynamic model recorded deviations of 17%–30%.
