Applications

N, N-Dimethylformamide is commonly used as a solvent. 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.

Notes

Residue after evaporation 5ppm, H{2}O<100ppmReaction with sodium hydride gives exothermic decomposition at low temperatures. Keep container tightly closed in a dry and well-ventilated place.
