Extraction of disperse blue 79, red 153, and yellow 119 with supercritical carbon dioxide was investigated, respectively, at 393.2 K and 30 MPa over a wide range of contact times. The dissolution rates of these three dyestuffs were compared. Equilibrium solubilities were also measured over the temperature and pressure ranges of 353.2–393.2 K and 15–30 MPa. As evidenced from the experimental results,...
