Solubility of triolein in supercritical carbon dioxide by using continuousflow system and correlation with pressure, temperature and density

The solubility of triolein in supercritical carbon dioxide (SCCO2) was meas ured by a continuous flow system at various temperatures (313, 323, 333 and 343 K) and pressures (15, 20 and 25 MPa). The solubility of triolein incre ases with experimental pressure. The obtained data were compared with previ ous investigations. At 15 MPa, the solubility is considerably governed by t emperature (343-313 K), i. c. 10(2) fold change of solubility. On the other hand, at 25 MPa, which is fully mature supercritical conditions, the influ ence of temperature on the solubility become weaker. Under constant pressur e conditions, solubility of triolein decreases gradually with increasing te mperature. Solubility is correlated well with the estimated density, accord ing to Bender (1970).
