HCON (CH3)2
Uses:
Solventor Resin:DMF is widely used in the production and processing of polymers. Spinning solvent for polyacrylonitrile fibre and polyurethane fibre (spandex) and processing solvent for production of polyurethane artificial and synthetic leather are some of the examples of commercial application.
DMF is also used for solution of polyamides (nylon) and for the production of heat-resistant wire enamels (polyamides, polyamideimides, polyesteramides etc.)
Selective Extractant:
Solvent for absorption of acetylene:DMF is used for the separation and refining of acetylene from crude olefin gas.
Solvent for absorption of dienes: DMF is used in extracting butadiene from the C4distillate obtained by naphtha cracking, etc. and in separating isoprene from C5 distillate.
Solvent for eliminating acid gas: DMF is also used as a solvent for recovery of H2S or S02 or elimination of HCl , Cl, HBr, etc. in hydrocarbons.
Solvent for extracting aromatics: DMF is also used in extracting solvent of aromatic hydrocarbons in petroleum refining.
Solvent for storing in cylinders: Gases like acetylene that are difficult to liquefy and handle safely can be stored and transported easily by dissolving them in DMF with a porous carrier solid (for example Calcium Silicate)
Solvent for Reaction: DMF is widely used as a solvent for reaction. Generally acetylation, chlorination. sulfonation and various condensation and polymerization reactions are among those where DMF is used as a solvent.
Solvent for Production of Pharmaceuticals:DMF is an excellent solvent for sulfonamide, vitamins, nitrofuran, quinoline, adrenaline, amine chlorides, etc. It is used in the production of pharmaceuticals widely as a reaction solvent, extracting solvent and crystallizing bath.
Dyestuff and Pigment: DMF easily dissolves basic dye pigments, nitroso pigments, phthalocyanine pigments azo pigments, and acid dye metal salts. It is also used as a solvent of colouring agent or an infiltrating ink for various films, wood, leather, resins, etc.
Paint Remover: DMF, alone or as mixed with methylene chloride, is used as a remover of varnish or lacquers.
