Abstract:	Reasonable estimates of ternary vapor-liquid equilibrium can be obtained by using the corresponding liquid-liquid equilibrium (LLE) data with the NRTL, LEMF and UNIQUAC models. The overall average absolute deviation in vapor phase concentration for seven such systems is 0.028.: Use of the UNIFAC method gives erratic predictions suggesting caution when applied to such systems. Combination, however, of the LLE data and the UNIFAC method gives the best results with a deviation of 0.020 Prediction of binary VLE behavior from LLE data yields also reasonably good results.
