Abstract
Equilibrium data are reported for the extraction of phenol at 288, 293 and 298 K with n-butyl acetate (NBA), acetophenone (AP) and mixtures of NBA + AP and methyl isobutyl ketone (MIK) + AP. A synergistic behaviour is observed for the system phenol-water-(NBA/AP). Several equations have been used to correlate the experimental data: van't Hoff, Redlich-Kister and other polynomial equations. Reported data were compared with those available in the literature.
