Abstract

The liquid–liquid equilibrium (LLE) data were measured for the ternary systems of water + methanol + ethyl levulinate, water + ethanol + ethyl levulinate, and water + n-butanol + n-butyl levulinate in a temperature range of 298.15 K to 328.15 K and at 101.3 kPa. Among the investigated mixtures, the ethyl levulinate-containing systems are categorized as a type-I LLE and their areas of two-liquid-phase region decreases with increasing temperature. The ternary system of water + n-butanol + n-butyl levulinate behaves as a type-II LLE and interestingly its area of two-liquid-phase region increases with an increase of temperature over the experimental condition. These new LLE tie-lines data were correlated accurately with the NRTL model.
