Description of DMAC:

N, N-dimethyl acetamide, referred to as DMAC, is an aprotic high-polarity solvent, with a slight ammonia smell, strong solubility, can be dissolved in a wide range of substances, and water, aromatic compounds, ketones, alcohols and other arbitrarily miscible, and can activate the compound molecule, so widely used as a solvent and catalyst. In the solvent as high boiling point, high flash point, high thermal stability, chemical stability of the solvent.

Application of DMAC:

This product is mainly used as a solvent for synthetic fiber (acrylonitrile) and polyurethane spinning and synthetic polyamide resin. It is also used as an extractive distillation solvent for separating styrene from C8 fraction, and is widely used in polymer film, coating and medicine. aspect. It is currently used in large quantities in medicines and pesticides to synthesize antibiotics and pesticides. It can also be used as a catalyst for the reaction, an electrolytic solvent, a paint scavenger, and various crystalline solvent adducts and complexes.
