By combining a pseudo-binary model with the Barkers method
it ispossible to predict the vapor phase mole fractions of a three-component salt-containing system from the relative P-T-x
data. The predicted values were compared with the experimental ones
point by point
to test the thermody-narnic consistency of VLE data. The isobaric VLE data for alcohol (ethanol
isopropanol)-water-salt(CaCl2
KAc)systems were tested
and good results were obtained. The success in predicting vapor phase mole fractions from P-T-x data paves the way for improving the determination of VLE for salt-contain-
