ABSTRACT
The liquid liquid equilibrium (LLE) properties were measured for the ternary systems ofwater + methanol + dimethyl adipate,water + adipic acid monomethyl ester + dimethyl adipate andwater + methanol + dimethyl glutarate at temperatures ranging from 298.15 to 318.15Kunder atmospheric pressure. Each ternary system exhibited type-I LLE behavior and the region of heterogeneity was found to increase with a decrease of temperature. These new LLE data were correlated with the NRTL model and also used to examine the validity of various versions of the UNIFAC models.
