The liquid-liquid equilibrium for the quaternary system of o-xylene(1)+water(2)+butyric acid(3)+ethyl acetate(4) was measured at 25 ℃ and atmospheric pressure. Binodal curves, tie-lines, distribution, and selectivity for the quaternary system have been determined in order to investigate the effect of binary solvents, o-xylene and ethyl acetate, on extracting butyric acid from aqueous solution. In addition, these experimental tie line data were also compared with the values predicted by the UNIFAC model. It is found that UNIFAC group interaction parameters used for LLE could not provide a good prediction.
