Dimensionless analysis was used to develop a correlative dimensionless solubility (DS) model and a predictive dimensionless solubility (pDS) model for estimating solid solubilities in supercritical carbon dioxide. Solubilities of 20 organic compounds made up of 685 data were used in developing the DS model and an additional 10 organic compounds were used for assessing the pDS model. Average relative deviation (ARD) in logarithmic solubility for literature model correlations were: Jouyban (2.06%), Hozhabr (2.09%), Jafarinejad (2.27%), Chrastil (2.49%), and Mendez-Santiago–Teja (3.46%). The proposed DS model had an ARD of 2.35% and the pDS model had an ARD of 10.5%. When the pDS model was optimized to the entire database, an ARD of 10.3% was obtained. The pDS model requires only pure solute properties (melting point, molar volume, entropy-based solubility parameter) and pure CO2 density for predicting solubility of solids in supercritical CO2.
