Abstract
Liquid–liquid equilibrium (LLE) data for the methyl isobutyl ketone + o-cresol + water ternary system have been experimentally measured from 298.2 to 323.2 K below 101 kPa. The measured LLE data were verified to be highly consistent through the Othmer–Tobias and Hand equations. The extraction efficiency of methyl isobutyl ketone for o-cresol was assessed by the distribution coefficient and separation factor. The experimental results correlated well with two excess Gibbs energy models: non-random two-liquid and universal quasi chemical, which also yielded binary interaction parameter.
