Dimethylformamide (DMF) or dimethyl formamide, a clear, colorless liquid with a high boiling point, is soluble in water and has a odor close to that of amines. It is commonly used to synthesize organic compounds or as a solvent at low evaporation rates.
Dimethylformamide (DMF) production method
The substance was first developed by the French chemist Albert Verley in 1893 using a mixture of diaminyl amine hydrogen chloride and potassium formate. Dimethyl formidamide can also be produced by combining methyl formate and dimethyl amine, or by using the reaction of dimethyl methylamine with carbon monoxide. Although it may seem somewhat impractical, it can also be triggered by the reaction of supercritical carbon dioxide with ruthenium-based catalysts.
Dimethylformamide (DMF) properties
Dimethyl formaldehyde (DMF) is an aprotic bipolar organic solvent and a hygroscopic liquid that is an ideal solvent due to its high electrical constant, high solubility, and low volatility. It can mix with water and most organic liquids and is not resistant to strong acids and bases, and also reacts strongly with concentrated sulfuric acid and nitric acid foam, which may even cause an explosion.
Acidic or game impurities accelerate the degradation of this material, which can be eliminated by freezing the samples decomposed with inert gases or sonicizing the pressurized samples.
Dimethylformamide (DMF) applications
It is used in the production of solvent dyes as a raw material, in the textile industry as a solvent in polyurethane coatings, in synthetic leather industries as auxiliary materials, in the pharmaceutical industry as a solvent for drug production, in the production of acrylic and plastic fibers, In monomer, the base of polyamide film production is used in adhesive and insulation industries, in the manufacture of nanocomposite membranes, water treatment processes, in the production of pesticides, in surface coatings, etc.
