The PU is produced in a process reliant on the solvent N,N- the textile industry supply chain. Commonly DMF is a polar hydrophilic aprotic solvent with a high boiling point. It facilitates reactions that follow polar mechanisms, such as SN2 reactions. It is also used in the manufacturing of solvent dyes as an important raw material.

Request For Quotation. It caused contact dermatitis in a technician at an epoxy resin factory and can provoke alcohol-induced flushing in exposed subjects.
Dimethylformamide is primarily used as an industrial solvent. Dimethylformamide solutions are used toprocess polymer fibers, films, and surface coatings; to permit easy spinning of acrylic fibers; to produce wire enamels, and as a crystallization medium in the pharmaceutical industry.
DMF can also be used for formylation with alkyllithium or Grignard reagents. It is used as a reagent in Bouveault aldehyde synthesis and also in Vilsmeier-Haack reaction. It acts as a catalyst in the synthesis of acyl chlorides. It is used for separating and refining crude from olefin gas. DMF along with methylene chloride acts as a remover of varnish or lacquers. It is also used in the manufacture of adhesives, fibers and films.
N,N-Dimethylformamide DMF is a solvent with a low evaporation rate, useful for preparing solutions with a variety of hydrophobic organic compounds used in molecular biology applications. It was also used in feruloyl esterase activity assay in molds exhibiting high activity of the enzyme.
The world-wide consumption of DMF in was approximately , metric tonnes and most of that was used as an industrial solvent. In the synthesis of organic compounds. Solvent for Orlon and similar polyacrylic fibers.
Wherever a solvent with a slow rate of evaporation is required. Has been termed the universal organic solvent. Slightly less dense than water. Vapors heavier than air.
