N, n-dimethylformamide (DMF) is a colorless liquid with a distinctive pungent odor. Properties:
1. Density: The density of DMF is 0.944 g/mL, indicating its weight ratio relative to water.
2. Solubility: DMF is very soluble in water and can be miscible with many organic solvents (such as alcohols, ethers, ether alkanes, aromatics, etc.). Due to its good solubility, DMF is often used as a solvent or medium.
3. Stability: DMF is sensitive to light and air and is susceptible to oxidation and decomposition. Under high temperature, light, or prolonged storage conditions, DMF may break down to form toxic or harmful gases.
4. Acid and alkali: DMF is a strong alkaline solvent that can react with acid to form salts. It can react with many strong acids to form the corresponding DMF salt.
5. Combustibility: DMF can be burned to produce combustion products such as carbon dioxide, water. In an open flame, DMF may produce toxic gases when burned.
N, N-dimethylformamide (DMF) is a commonly used organic solvent with strong solubility and good stability. It is widely used in the field of chemistry. DMF is often used as a solvent in organic synthesis. Its solubility is good, can dissolve a variety of organic compounds, widely used in organic synthesis reaction. DMF can react with a variety of organic compounds, such as reacting with acylation reagents to produce esters and reacting with aromatic compounds to produce amides. Secondly, DMF also has applications in the polymer industry. It can be used as a reaction solvent for polymer compounds such as polyurethane, phenolic resin and polyamide. DMF can also be used to synthesize cellulose dissolving pulp, paint, coatings and other solvents. In addition, DMF can also be used as an electrolyte solvent. Its polarity and stability can be used as an electrolyte solvent in lithium-ion batteries, solar cells and other devices. In the preparation of nanomaterials, DMF can be used as a solvent or reaction medium for the synthesis of nanomaterials, and its particle size and morphology can be adjusted.
