ABSTRACT

Liquid-liquid equilibria (LLE) of nitrobenzene-sulfuric acid-water and nitrobenzene-nitric acid-water systems were experimentally determined at 298.15 K. The NRTL and UNIQUAC models were used to correlate the experimental data. The fit of these models to the experimental data were very good, and the root-mean-square deviations for both the systems were found to be less than 1 %. It was observed that the solubility of both acids in the organic phase and the solubility of nitrobenzene in the aqueous phase increased with the increase in concentration of acid in the mixture.
