What is DMF solvent?
Dimethylformamide (DMF) is a clear, colorless, hygroscopic liquid with a slight amine odor. The solvent properties of DMF are particularly attractive because of the high dielectric constant, the aprotic nature of the solvent, its wide liquid range and low volatility. It is frequently used for chemical reactions and other applications, which require a high solvency power. The product is known as a universal solvent.
What is THF solvent?
Tetrahydrofuran (THF) is a clear, colourless, organic compound with an ether-like odour and the formula (CH2)4O. It is primarily used as a precursor to polymers including for surface coating, adhesives, and printing inks. It is water-miscible and has a low viscosity making it a highly versatile solvent used in a variety of industries.
What is the difference between DMF and THF Solvent?
| Feature | Tetrahydrofuran (THF) | Dimethylformamide (DMF) |
|---|---|---|
| Chemical Structure | Cyclic ether (C₄H₈O) | Amide (HCON(CH₃)₂) |
| Polarity | Polar | Highly polar |
| Key Solvent Property | Excellent for organometallics (Grignard), good for non-polar compounds. | Excellent for polar compounds, polymers, and SN2 reactions. |
| Primary Uses | Polymerization solvent, PVC cement, Grignard reactions. | Solvent for polyacrylonitrile (acrylic fibers), pharmaceuticals, and peptide synthesis. |
| Miscibility with Water | Fully miscible | Fully miscible |
| Hazards | Flammable, forms explosive peroxides. | Less flammable, but a reproductive toxin and can be absorbed through the skin. |
