Abstract
A simple and rapid method has been developed to determine the solubility of organic compounds in supercritical CO 2 by coupling a saturation cell directly to a flame ionization detector. After temperature equilibration, the detector's response to cell pressure changes is rapid, which allow several solubility determinations to be performed per hour. Solubilities determined by this method are in good agreement with published data obtained from gravimetric or spectroscopic methods for anthracene and tripalmitin. Solubility increases with raising temperature from 40 to 200 o C (at constant pressure) are usually larger for the above solutes than solubility increases with raising pressure from 150 to 400 bar (at constant temperature)
