In this study, the measurement and correlation of the solubility of the rhodamine B in supercritical carbon dioxide (scCO2) with or without a cosolvent were determined. The results were obtained using a flow-type apparatus, at 308.15 and 318.15 K, in a pressure range 8.0 - 24.0 MPa. The results show that, at a fixed temperature, the solubility of the dye in scCO2 fluids increases with increasing pressure. In the presence of 5 mol% methanol as a cosolvent, the solubility of dyes increased significantly. The experimental data correlated with the Chrastil and Sovova equations.
