Liquid-liquid equilibria (LLE) for the system ethanol (1) + water (2) + tripotassium citrate (3) were measured at temperatures of (288.15, 298.15, and 308.15) K. The dependence of temperature on the LLE data is very small in the temperature range studied, but the slopes of the tie lines were found to decrease slightly with decreasing temperature. The binodal curves at each temperature were well fitted by a nonlinear equation with four parameters, and the tie line data were successfully correlated with the Othmer-Tobias and Bancroft equations. The LLE results were correlated using the nonlinear and Othmer-Tobias equations in addition to the nonlinear and Bancroft equations. Both correlations showed close agreement with experimental values, with (0.27 and 0.26) % as the average deviations of three temperatures, respectively.
