Liquid–liquid equilibrium (LLE) date for the ternary systems of {water + 1-propanol + dibutyl ether (DBE)} and (water + 1-butanol + DBE) were determined at T = (293.15, 303.15, 308.15) K under atmospheric pressure. Distribution coefficients and separation factors of 1-propanol in the mixtures were calculated and are discussed. The influence of temperature on the liquid phase regions was analyzed. In addition, the experimental values were correlated well with the modified and extended UNIQUAC models; the modified UNIQUAC model represents the data better than the extended UNIQUAC model.
