| titleOfInvention | Method for producing N, N-dimethylacetamide (DMAC) |
| abstract | In a method for producing N, N-dimethylacetamide (DMAC) by continuously reacting methyl acetate (MeOAc) and dimethylamine (DMA) in the presence of a basic catalyst, MeOAc is used as a methanol solution, In addition, after-treatment by continuous distillation, first, methanol and possibly other low-boiling substances are separated in the column A via the top of the column, and the bottom product discharged from the column A is fed to the column B. In particular, a method for producing N, N-dimethylacetamide is characterized in that DMAC having a purity of 99.7% by mass or more is separated through a side discharge part. |
