The Peng-Robinson and Soave–Redlich–Kwong (SRK) equations of state are applied in this study to calculate the solubility of 1-hydroxy-9,10-anthraquinone,in supercritical carbon dioxide at temperatures ranging from 308 to 338 K and pressures in the range of 12 to 35 MPa. Published solubility data of these compound have been fitted to these equation of state in combination with one and two parameters van der Waals mixing rules and with combination with the Panagiotopoulos-Reid (mrPR) mixing rule. The binary interaction parameters of models are obtained by using Matlab software.
