3.Application
DMAC is mainly used as synthetic fibers (PAN) and polyamide resin, polyurethane and synthetic spinning solvent, but also for separation of styrene from the C8 fraction of extractive distillation solvent, and is widely used in polymer thin films, coatings and medical aspects. Medicine and pesticides currently used on a large number of synthetic antibiotics and pesticides. Also be used as catalysts, electrolysis solvent, paint stripper and a variety of crystalline solvent adduct and complex.
