The　study　on　liquid-liquid　equilibrium　(LLE)　is　important　for　N,　N-dimethylformamide　(DMF)　recovery　from　wastewater　by　extraction.　In　order　to　achieve　the　basic　data　for　further　study,　the　LLE　experiments　of　DMF-chloroform-water　ternary　system　at　30C,　35C,　40C　and　atmospheric　pressure　were　carried　out　in　an　equilibrium　cell.　The　equilibrium　concentrations　were　determined　by　gas　chromatography.　The　NRTL　and　UNIQUAC　models　were　adopted　to　correlate　the　liquid-liquid　equilibrium　data　of　the　studied　system,　and　the　model　parameters　were　estimated　by　the　simplex　method.　The　active　coefficients　in　the　LLE　equations　were　calculated　by　the　NRTL　and　UNIQUAC　models,　and　the　calculated　LLE　data　of　DMF-chloroform-water　ternary　system　were　compared　with　the　experimental　data.　Based　on　the　NRTL　and　UNIQUAC　models,　the　calculated　equilibrium　compositions　of　the　studied　ternary　system　are　in　good　agreement　with　the　experimental　data.　The　total　mean　absolute　deviations　of　NRTL　and　UNIQUAC　models　are　0.0032　and　0.0033,　respectively,　and　the　total　mean　relative　deviations　of　them　are　2.60%　and　2.97%,　respectively.
