ABSTRACT
In the present work, liquid-liquid equilibria (LLE) data for ternary systems, water + propionic acid or butyric acid + methyl tert-butyl ketone (MTBK), at (298.15 and 323.15) K under atmospheric pressure were measured. The reliability of the experimental LLE data was verified by the Othmer-Tobias and Hand equations. The distribution coefficient, together with the selectivity, was used to assess the extraction performance of MTBK. The universal quasichemical activity coefficient (UNIQUAC) and nonrandom two-liquid (NRTL) models were used to correlate the experimental tie-line data, and binary interaction parameters for relevant process simulation were thus obtained.
