N. N-Dimethylacetamide Chemical name: N, N-dimethylacetamide Preparation source: dimethylamine, glacial acetic acid Product nature: A colorless transparent liquid that can be mixed with organic solvents such as water, alcohol, ether, ester, benzene, trichloromethane, and aromatic compounds at will. Quality indicators: Chromatographic content ≥ 99.9%; Water content PPm ≤ 100; Acid content (as HAC) PPm ≤ 80; Alkali content (as DMA) PPm ≤ 5; Iron content PPm ≤ 0.05; Conductivity (20 ℃) μ S/cm ≤ 0.5 Main use: Used as a solvent for heat-resistant synthetic fibers, plastic films, coatings, pharmaceuticals, and acrylonitrile spinning. Used for the synthesis of polyimide, polysulfonamide, and other polymer compounds, as well as for the film-forming and spinning of synthetic resins, and for the synthesis of Yaowu. Packaging and storage: net content of 190 kg/plastic drum; It should be sealed and stored in a cool and dry place, avoiding water absorption and sunlight exposure. It should not be close to fire sources and should be handled with care during transportation. Toxicity introduction: It has a strong irritant effect on the eyes, skin, and respiratory mucosa of humans. Frequent exposure to DMAC can cause abnormal symptoms in the liver, kidneys, heart, blood vessels, nerves, and other systems. DMAC is more toxic than dimethylformamide, with a maximum allowable concentration of 20 ppm in the air. Each country has established relevant standards to limit the maximum allowable concentration of * in the air of the workplace. Labels: DMAC solvent, acetamide, dimethylacetamide, acetyldimethylamine
