Estimation of a specially synthesized dye, viz. 1-(4- aminophenylazo)-2-naphthol (APAN) and C.I. Disperse Yellow 82 (DY82) solubilities in supercritical carbon dioxide with equation of states (EOSs)

The solubility of two dyes, a specially synthesized dye, viz. 1-(4-aminophenylazo)-2-naphthol (APAN) and C.I. Disperse Yellow 82 (DY82) in supercritical carbon dioxide have been correlated with two equation of state. All critical properties have been estimated with a group contribution method (GCM). Solubility data for these materials never has been correlated using an equation of state (EOS). In this work, the aim is correlating reported data with a new EOS and comparing obtained result with Peng-Robinson EOS. The calculated results show that M-factor EOS is more accurate than Peng-Robinson EOS.
