Abstract: In the past few years, new processes for citric acid recovery have been studied. Among these processes, liquid-liquid extraction has had special attention. The extraction process is attractive due to the fact that, if a good solvent is used, it presents high selectivity and efficiency, it does not affect the thermal stability of products, and it requires low energy consumption. In this work, experimental data for the liquid-liquid equilibria of water-citric acid-solvent systems were obtained. The following solvents were tested: 2-butanol, 1-butanol, and mixed solvents containing those alcohols and tricaprylin. The parameters for the NRTL and UNIQUAC models were obtained by fitting the thermodynamic models to the experimental data.
