Overview

N,N-Dimethylacetamide, also known as acetyldimethylamine, abbreviated as DMAC, is an aprotic highly polar solvent with a slight ammonia odor. It has strong solvency and a wide range of soluble substances. It can be miscible with water, aromatic compounds, esters, ketones, alcohols, ethers, benzene, trichloromethane and other substances in any proportion, and can activate compound molecules. Therefore, it is widely used as a solvent and catalyst. 

As a solvent with high boiling point, high flash point, high thermal stability and chemical stability, it can be used as spinning solvent for polyacrylonitrile, and solvent for synthetic resins, natural resins, copolymers such as vinyl formate and vinyl pyridine, and aromatic carboxylic acids. As a catalyst, it can be used in processes such as heating urea to produce cyanuric acid, reacting alkyl halides with metal cyanides to produce nitriles, reacting sodium acetylide with alkyl halides to produce alkyl alkynes, and reacting organic halides with cyanates to produce isocyanates. N,N-dimethylacetamide can also be used as electrolytic solvent, solvent for photographic couplers, paint remover, raw material for organic synthesis, pesticide and pharmaceutical raw material, extractive distillation solvent for separating styrene from C8 distillate, etc.
