In this work, experimental tie-line results and solubility curves were obtained for the ternary systems (water + acetic acid + methyl isobutyl ketone (MIBK)) and (water + lactic acid + methyl isobutyl ketone) at T = 294.15K and atmospheric pressure. The consistency of the values of the experimental tie-lines was determined through the Othmer-Tobias and Hands correlations. For the extraction effectiveness of solvents, the distribution and selectivity curves were plotted. Additionally, these experimental tie-line data were correlated with the NRTL model, from which the interaction parameters were derived using a combination of the homotopy method and genetic algorithms. The root mean square deviation (RMSD) values between observed and calculated mass percents for the systems water-lactic-MIBK and water-acetic acid-MIBK were found to be 4.657% and 8.580%, respectively. The results indicate that MIBK is a preferable solvent for the separation of acetic and lactic acid from aqueous solutions. This combined approach of using homotopy continuation and genetic algorithms can be extended to predict liquid-liquid equilibrium and binary interaction parameters for other liquid-liquid and vapor-liquid systems.
