ABSTRACT

Liquid-liquid equilibrium data for ternary systems (water + o-, m- or p-cresol + methyl butyl ketone) were measured at 298.2 and 313.2 K under atmospheric pressure by gas chromatography. Distribution coefficients and separation factors were calculated to evaluate the extracting performance of methyl butyl ketone. For each system, the Hand and Othmer-Tobias equations were used to assess the quality of LLE data. These data were also correlated using NRTL and UNIQUAC models to yield binary interaction parameters for designing or optimizing cresols extracting process.
