Product Description Dimethylformamide DMF is a clear, colorless, hygroscopic liquid with a slight amine odor. DMF is widely used as a solvent, reagent and catalyst in the synthetic organic chemistry. It is also used as a solvent dimthylformamide peptide coupling for pharmaceuticals, in the development and production of pesticidesand in the manufacture of adhesivessynthetic leathersfibers, films, and surface coatings.
Spectral Database for Organic Compounds. As for most amidesthe spectroscopic evidence indicates partial double bond character for the C-N and C-O bonds. This page was last edited on 12 Decemberat The high solubility of polyacrylonitrile in DMF, together with the good miscibility of Dimethglformamide in water makes DMF the preferred solvent for the production of acrylic fibers.
Dimethylformamide – Wikipedia
Also for the dimethykformamide of aromatics, which can be easily dissolved by DMF from aliphatic hydrocarbons. The pharmaceutical industry uses DMF as a reaction and crystallization solvent because of its exceptional solvency parameters.
Authorized Distributors Please select a region and country for diethylformamide list of authorized distributors. Lethal dose or concentration LDLC:. In the petrochemical industry DMF is used for the purification of acetylene from ethylene and butadiene from C4 streams. NN -Dimethylformamide .

Although currently impractical, DMF can be prepared from supercritical carbon dioxide using ruthenium -based catalysts. A new method for the preparation of secondary and tertiary p -alkylamino-benzaldehyde]. DMF was first prepared in by the French chemist Albert Verley 8 January — 27 Novemberby distilling a mixture of dimethylamine hydrochloride and potassium formate.
DMF is also used as carrier for inks and dyes in various printing and fiber-dying applications. Encyclopedia of Reagents for Organic Synthesis.
Return to previous page. Orders subjected to minimum order quantity. Retrieved 27 June The Royal Society of Chemistry. The acute LD50 oral, rats and mice is 2. It is frequently used for chemical reactions and other applications, which require a high solvency power.
The primary use of DMF is as a solvent with low evaporation rate. On a pilot plant scale, on the other hand, several accidents have been reported.
Eastman | Dimethylformamide (DMF)
The solvent properties of DMF are particularly attractive because of the high dielectric constant, the aprotic nature of the solvent, its dimetuylformamide liquid range and low volatility.
It facilitates reactions that follow polar mechanisms, such as S N 2 reactions. Due to the high solubility of SO 2 in DMF, exhaust combustion streams from high sulfur containing fuels can be purified with CO 2 being recovered. Dimethylcormamide like polyvinylchloride, vinylchloride- vinylacetate copolymers and some polyamides are also readily dissolved in DMF. On a laboratory scale any thermal runaway is usually quickly noticed and brought under control with an ice bath and this remains a popular combination of reagents.
LC 50 median concentration. DMF is prepared by combining methyl formate and dimethylamine or by reaction of dimethylamine with carbon monoxide. Organolithium compounds react with DMF to give, after hydrolysis, aldehydes.
Also the spinning of polyurethane based elastomers is performed from DMF based solutions. Dimethylformamide is odorless whereas technical grade or degraded samples often have a fishy smell due to impurity of dimethylamine. DMF is miscible with water.
