Isobaric vapor–liquid equilibrium of trifluoroacetic acid + water, trifluoroacetic acid + ethyl trifluoroacetate and ethyl trifluoroacetate + ethanol binary mixtures

Vapor–liquid equilibrium data for ethyl trifluoroacetate + trifluoroacetic acid, ethyl trifluoroacetate + ethanol, and trifluoroacetic acid + water at the pressure 101.3 kPa were measured with a modified Rose still. The thermodynamic consistency of the VLE data was confirmed by Herrington’s method. The VLE data were correlated by the NRTL and Wilson models with satisfactory results, and the interaction parameters of these mixtures were estimated.
