Prediction of N-phenylacetamide, 2-methyl-N-phenylacetamide and 4-methyl-N-phenylacetamide solubilities in supercritical carbon dioxide with an equation of state (EOS)

In this study, the solubility of N-phenylacetamide, 2-methyl-N-phenylacetamide and 4-methyl-Nphenylacetamide in supercritical carbon dioxide have been correlated with M-factor equation of state. All critical properties have been estimated with a group contribution method (GCM). Solubility data for these materials has been correlated using Peng-Robinson EOS and Soave- Redlich-Kwong EOS. It is worthwhile to model the solubility of these materials with a new EOS. So, In this work, the aim is correlating reported data with a new EOS and comparing obtained result with Peng-Robinson EOS and Soave-Redlich-Kwong EOS. The calculated results show that new EOS is more accurate than Peng-Robinson EOS and Soave-Redlich-Kwong EOS. It can be employed to speed up the process of SCF applications in industry.
