DMF (N,N-Dimethylformamide CAS 68-12-2) and DMAC (N,N-Dimethylacetamide CAS 127-19-5) are common organic solvents that are widely used in the chemical, pharmaceutical, electronics and fiber industries. Their main differences are as follows:
Physical properties differences
| Property | DMF | DMA |
|---|---|---|
| Molecular Weight | 73.1 g/mol | 87.1 g/mol |
| Boiling Point (1 atm) | ~153 °C | ~165 °C |
| Melting Point | -61 °C | -20 °C |
| Density (20 °C) | 0.948 g/mL | 0.937 g/mL |
| Polarity (Dielectric Constant, ε) | ~38.3 | ~37.8 |
| Solubility | Miscible with water, alcohols, ethers, and most organic solvents. | Miscible with water and organic solvents. |
| Volatility | More volatile than DMA (lower boiling point). | Less volatile (safer for high-temperature reactions, as it evaporates more slowly). |
differences of Applications (Industrial)
Dimethylformamide DMF: DMF Solvent is mainly used in pharmaceutical synthesis, pesticides, coatings, electronics industry, textile industry (such as wet spinning of polyacrylonitrile fiber).
Dimethylacetamide DMAC: Solvent DMAC is mainly used for dissolving polymers (such as aramid, polyurethane), synthetic medicine, solvent extraction and so on.
