Vapor-liquid　equilibrium　data　of　chloroform-N,N-dimethylformamide　(DMF)　system　are　first　determined　at　101.3　kPa　by　using　the　equilibrium　distiller.　The　binary　VLE　data　are　correlated　by　NRTL,　UNIQUAC　and　Wilson　models　respectively.　The　activity　coefficients　are　obtained　by　the　simplex　method.　Average　relative　deviations　between　the　calculated　values　with　the　three　models　and　the　experimental　data　of　gas　phase　mole　fraction　are　all　less　than　2.24%,　and　average　relative　deviations　between　calculated　values　and　the　experimental　data　of　temperature　are　all　less　than　0.62%.　The　root　mean　square　deviations　(RMSD)　of　compositions　and　temperature　are　less　than　0.005　and　0.7　K,　respectively.　Thermodynamic　consistency　of　the　experimental　data　is　tested　according　to　Herington　method.　It　is　demonstrated　that　calculated　results　of　NRTL,　UNIQUAC　and　Wilson　equations　are　all　in　good　agreement　with　the　experimental　data,　and　that　azeotrope　behavior　is　not　found　for　the　binary　system　of　chloroform　+　DMF　The　results　not　only　provide　the　basis　for　analysis　and　design　of　distillation　process,　but　also　promote　the　development　of　new　technology　to　recover　DMF　from　wastewater.　(C)　2009　Elsevier　B.V.　All　rights　reserved.
