A　novel　green　process　was　developed　for　the　recovery　of　N,N-dimethylformamide　(DMF)　from　the　acid-containing　DMF　solution　by　adding　dimethylamine　into　the　acid-containing　DMF　system　during　the　＇primary　distillation-continuous　reaction-secondary　distillation＇　process,　with　N,N-dimethylacetamide　(DMAC)　produced　as　by-product.　The　laboratory　research　and　the　pilot-scale　test　were　carried　out.　The　results　show:　dimethylamine　can　break　the　interaction　between　DMF　and　acetic　acid;　the　crude　DMF　with　purity　of　95%　and　no　acid　was　produced　during　the　primary　distillation　process,　and　the　recovery　of　DMF　was　about　80%;　the　acid　reacted　with　dimethylamine,　producing　DMF　and　DMAC,　with　a　conversion　of　96%,　and　the　concentration　of　acid　in　the　mixture　was　reduced　to　1.4%　after　the　reaction;　the　distillate　with　47%　DMF　and　the　residue　with　97.7%　DMAC　were　obtained　from　the　reaction　mixture　in　the　secondary　distillation　process.　©　2019,　Editorial　Office　of　FINE　CHEMICALS.　All　right　reserved.
