Solubility assessment of castor (Ricinus communis L) oil in supercritical CO<inf>2</inf> at different temperatures and pressures under dynamic conditions

A simple dynamic technique was used to obtain the solubility of castor oil in supercritical carbon dioxide. The solubility was measured at temperatures ranging from 313 to 335K and pressures from 20 to 36MPa. Under extraction conditions, the measured solubilities were in the range from 1.29×10-3 to...
