Correlation and Prediction of Vapor-Liquid Equilibrium for the Propylene Oxide-Ethanol-Water Ternary System

Abstract:

The vapor-liquid equilibrium (VLE) data for the binary systems ethanol-water (1), propylene oxide (PO)-ethanol (2), PO-water (3) and the ternary system PO-ethanol-water (4) were determined at 101.3kPa. The binary VLE data measured passed the thermodynamic consistency verification. The experimental VLE data of the binary systems were correlated with the nonrandom two-liquid (NRTL) models. The results show that the values of molar fraction of the ternary system (4) in vapor phase from the binary NRTL parameters agree well with the experimental data.
