© 2021 American Chemical Society.Liquid–liquid equilibrium (LLE) data for the mixture 2–methyl–2–butanol + water + ethylbenzene were measured at 303.15, 313.15, and 323.15 K at atmospheric pressure. The quality of the experimental LLE data was tested by the mass balance between the feed and the conjugated phases. The extraction capacity of ethylbenzene was evaluated by selectivity (S). The experimental results show that S is more than 117, and it decreases with the content of 2–methyl–2–butanol in the water phase and equilibrium temperature. The binary interaction parameters for the NRTL and UNIQUAC models were derived from regression of the experimental LLE data. The root–mean–square deviations are no more than 1.27%. The consistency between the regressed binary interaction parameters and the experimental LLE data was verified using the topology of Gibbs energy of mixing surface analysis.
