Abstract

The solubility of triolein in supercritical carbon dioxide (SCCO2) was measured by a continuous flow system at various temperatures (313, 323, 333 and 343K) and pressures (15, 20 and 25MPa). The solubility of triolein increases with experimental pressure. The obtained data were compared with previous investigations. At 15MPa, the solubility is considerably governed by temperature (343-313K), i. e. 10102-fold change of solubility. On the other hand, at 25MPa, which is fully mature supercritical conditions, the influence of temperature on the solubility become weaker. Under constant pressure conditions, solubility of triolein decreases gradually with increasing temperature. Solubility is correlated well with the estimated density, according to Bender (1970).
