ABSTRACT

Boiling point data for the ternary system methanol + ethanol + dimethyl carbonate and its constituent binary systems were measured from 40.00 to 93.32 kPa using a modified Swietoslawski-type ebulliometer. Experimental data for the binary systems were correlated using the Wilson equation to determine vapor-liquid equilibria (VLE). The Wilson equation was also applied to the ternary system to predict VLE with parameters from the binary mixtures. Comparison between predicted and experimental boiling points for the ternary system showed that the Wilson equation provided useful estimates. The valley line, which was found in this system, was estimated using the Wilson binary parameters.
