The　isobaric　vapor-liquid　equilibrium　measurements　for　the　systems　of　2-butyl　acetate　with　three　chemicals　(methanol,　2-butyl　alcohol,　methyl　acetate)　were　determined　respectively　in　a　modified　Rose　still　at　101.33　kPa.　Thermodynamic　consistency　of　the　three　binary　vapor-liquid　equilibrium　data　had　been　confirmed　by　Herington　methods.　The　three　groups　of　experimental　data　were　all　correlated　with　NRTL　and　Wilson　models,　respectively.　The　binary　interaction　parameters　of　both　models　had　been　obtained　by　the　simplex　method.　The　NRTL　and　Wilson　equations　showed　low　deviation　with　respect　to　the　experimental　data.　©　2013　American　Chemical　Society.
