Abstract

The solubility of three disperse azo dyes, 4-(N,N-dimethylamino)-4’-itroazobenzene (D1), 4-(N,N-diethylamino)-4’-nitroazobenzene (D2) and Parared (D3) in supercritical carbon dioxide have been correlated with two equation of state. All critical properties have been estimated with a group contribution method (GCM). As far we know, solubility data for these dyes never has been correlated using an equation of state (EOS). Therefore, it is worthwhile to model the solubility of these disperse Azo dyes. In this work, the aim is correlating reported data with a new EOS and comparing obtained results with the results of Peng-Robinson EOS (PR-EOS) together with two adjustable parameter van der Waals mixing and combining rules. The calculated results showed that new EOS is more accurate than PR-EOS. It can be employed to speed up the process of SCF applications in industry.
