3, USES: main use: dimethyl formamide (DMF) as solvent of important chemical raw materials and excellent performance, dimethyl formamide is an extremely useful chemical raw materials, is also a kind of very useful good solvent. Dimethyl formamide for a variety of polymers such as polyethylene, PVC, polyacrylonitrile, polyamide, etc are all good solvent, can be used for polyacrylonitrile fiber synthetic fiber such as wet spinning, the synthesis of polyurethane; For plastic film making; Can also be used as paint removal agent; It also can dissolve certain low solubility of paint, make the paint with the characteristics of the dye. In the petroleum chemical industry, dimethyl amine can be used as gas absorption agent, used to separate and refined gas. In organic reactions, dimethyl formamide not only widely used as reaction solvent, is also the important intermediates in organic synthesis. Pesticide industry can be used to the production of chlordimeform. Pharmaceutical industry can be used for the synthesis of DianAn pyrimidine, doxycycline, cortisone, vitamin B6, and so on. Dimethyl formamide also have catalytic effect, lower the reaction temperature, the purity of the product improved. Although it was the "universal solvent", but also has its limitations. The high boiling point, 152 ℃, as solvent of many polymer materials is more appropriate, carefully choose in organic synthesis, often encounter not solvent to take off the net. Again, it can be mixed with water soluble, simple recycling solvent method is difficult to dehydration, at the cost of time, will wash off with water

4. Production and preparation methods: methanol and liquid ammonia catalysis, please refer to the relevant data for details

5. Hazard category: category 3.3 flammable liquids

6. Fire control measures: use capacitance-resistant foam, carbon dioxide, dry powder, sand and soil to extinguish the fire. Water can be used to keep the container cool at critical times.

7. First aid treatment: low toxicity: if it is splashed on clothes or skin, take off the clothes and rinse the skin with water. If it is splashed on eyes, lift the eyelid and rinse with flowing water or normal salt water for 15 minutes. If ingested, induce vomiting and seek medical advice

8. Packaging, storage and transportation: stainless steel pressure tank packaging can be used in steel drum (190kg/ drum) or plastic drum (190kg/ drum) with baking paint; Should be stored in a cool, ventilated warehouse, avoid light, heat insulation, sealed storage quality storage period of one year, atmospheric tank storage effect is not as good as the barrel, should not be stored for a long time; Transport as required for general dangerous goods
