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.　©　2015　Elsevier　B.V.
