Abstract

In this work, correlation of solute solubility in supercritical fluid in presence of co-solvent has been carried out using a new density-dependent empirical equation. The new model has five parameters for each system. The parameters of the new correlation have been obtained for various ternary systems including 1668 experimental solubility data. The overall percent of absolute average deviations (%AARD) are 1.57 and 2.35 using different density calculation methods The comparisons of the new equation and the published models show its good capability in calculating solute solubility in supercritical fluid in presence of co-solvent.
