It was found that the solubility of AAQ was ca . 3 times greater than EAQ at the same conditions. Finally,experimental data were correlated by the modified λ-h equation,in which a factor of the solvent composition was added.The results showed that the modified λ-h equation can be used to predict the solubility of AAQ in TMB/TOP system with an average relative deviation (ARD) of 5%.展开更多
