DMAC (Dimethylacetamide) is a versatile industrial solvent, offering strong dissolving power for both organic and inorganic compounds. Its full miscibility with water, ethers, esters, ketones, and aromatics ensures stable performance across pharmaceuticals, resins, fibers, and chemical manufacturing.

Product introduction
Dimethylacetamide, also known as n-dimethylacetamide (DMAC), is a high-boiling, polar, dipolar aprotic solvent widely used in chemical synthesis, polymer processing, fiber production, and pharmaceutical manufacturing. It is a colorless, hygroscopic liquid with excellent thermal and chemical stability, making DMAC a reliable choice for demanding industrial applications.
Dimethylacetamide exhibits outstanding solvency for a wide range of organic and inorganic compounds and is fully miscible with water, ethers, esters, ketones, and aromatic solvents. Due to its strong polarity, n-dimethylacetamide can function not only as a solvent but also as a reaction medium that improves reaction efficiency, helping manufacturers achieve higher yields and purer products within shorter processing cycles.

Key Industrial Applications of DMAC
Acrylic Fiber Production
DMAC is widely applied as a solvent in wet spinning processes for the production of acrylic fibers, ensuring uniform fiber structure and stable spinning performance.
Elastane (Polyurethane) Fibers
In the production of polyurethane-based elastane fibers, Dimethylacetamide is the solvent of choice due to its suitable evaporation rate and excellent compatibility with both wet and dry spinning processes.
Pharmaceutical Manufacturing
n-Dimethylacetamide is used as both a solvent and reagent in pharmaceutical synthesis, including:
X-ray contrast media production
Cephalosporin antibiotics manufacturing
Processes involving 7-ADCA (7-aminodeacetoxy-cephalosporanic acid) derivatives
Its high purity and chemical stability make DMAC suitable for pharmaceutical-grade applications.
Polymer, Film & Membrane Applications
Dimethylacetamide (DMAC) is an excellent solvent for polyimide resins in coatings and films. It is also widely used in the production of polysulfone-based dialysis membranes. A mixture of n-dimethylacetamide and lithium chloride is an effective solvent system for cellulose fibers in multiple industrial applications.
