DMF (N,N-Dimethylformamide) and DMAC (N,N-Dimethylacetamide) are common organic solvents that are widely used in the chemical, pharmaceutical, electronics and fiber industries. Their main differences are as follows:
What Is Dimethylacetamide (CAS 127-19-5)?
| Feature | DMAc (DMA) | DMF |
|---|---|---|
| Full name | N,N-Dimethylacetamide | N,N-Dimethylformamide |
| CAS number | 127-19-5 | 68-12-2 |
| Chemical group | Amide (acetamide) | Amide (formamide) |
| Boiling point | ~165–166°C | ~153°C |
| Odor | Mild, less pungent | Strong fishy/ammonia-like |
| Solvent strength | Slightly milder | Stronger solvent power |
| Stability | More thermally stable | Slightly less stable at high heat |
| Common use | Fibers, PU, coatings, membranes | Resins, pharmaceuticals, acrylics |
Chemical structure difference:
N,N-Dimethylacetamide DMAc (DMA) has an acetamide group (CH₃CON(CH₃)₂).
N,N-Dimethylformamide DMF has a formamide group (HCON(CH₃)₂).
Industrial application differences
N,N-Dimethylformamide DMF solvent: Used in the wet spinning of polyacrylonitrile fibers, as a solvent for acrylic plastics, and in peptide coupling reactions in pharmaceutical production.
N,N-Dimethylacetamide DMAc solvent: A preferred solvent for dissolving certain polymers, such as polyurethane. Due to its stability, it is commonly used in the production of synthetic fibers and films.
