Dimethyl acetamide (DMAC) is a member of the class of ace amides that is ace amide in which the hydrogen’s attached to the N atom have been replaced by two methyl groups respectively. It appears as a clear colorless liquid with a faint odor similar to ammonia.

· Dimethyl ace amide (DMAC) is a dipolar aprotic solvent used for many organic reactions and industrial applications. It is a versatile solvent due to its high boiling point and good thermal and chemical stability.
· Acrylic fibers- DMAC is applied as solvent in wet spinning processes for the production of acrylic fibers.
· Eastham fibers- In the production of polyurethane-based elasthane fibers, DMAC is the solvent of choice given its evaporation speed, whether it is used in wet or dry spinning processes.
· Pharmaceuticals- DMAC can be used both as a solvent and as a reagent in the production of various pharmaceuticals. In the production of novel x-ray contrast media, DMAC is used as a solvent. Cephalosporin’s, which are among one of the leading classes of antibiotics, are partly produced from derivatives of 7-ADCA (7-aminodeacetoxy-cephalosporanic acid). DMAC is used in the manufacturing process.
· Various polymers- DMAC is a good solvent for polyimide resins, both in coating and film production. It is also the ideal solvent for the production of dialyzer membranes, based on polysulfide’s. A mixture of DMAC and lithium chloride is a useful solvent for cellulose fibers in several applications.
