description Product Description
N-N-Dimethylacetamide (DMAC) is widely used as a solvent in the production of fibers, particularly acrylic fibers and polyurethane fibers. It is also employed in the pharmaceutical industry as a solvent for the synthesis of various drugs and active pharmaceutical ingredients. In the electronics industry, DMAC is utilized in the manufacturing of printed circuit boards and as a solvent for polyimide films. Additionally, it serves as a reaction medium in organic synthesis and polymerization processes. Its high solvency power and stability make it suitable for use in coatings, adhesives, and paint strippers. DMAC is also applied in the purification of gases, such as removing carbon dioxide from natural gas streams.
