Applications
N,N-Dimethylacetamide is used as a polar solvent in organic synthesis as well as in reactions involving strong bases such as sodium hydroxide. It is also used as a solvent for fibers like polyacrylonitrile, spandex, as an excipient in drugs viz. vumon, busulfex and in the adhesive industry. It finds application as a reaction medium in the production of pharmaceuticals, agrochemicals, dyes and plasticizers. It is widely used in polymer industry due to its high solving power for high molecular-weight polymers and synthetic resins. It plays an important role as a catalyst in various reactions viz. cyclization, halogenation, cynidation, alkylation and dehydrogenation and increases the yield of main products. It is also used as an extracting agent for oil and gases, in paint removers, in the production of photo-resist stripping compounds and as booster solvent in coatings.
Notes
