1,Used as analytical reagent and solvent of vinyl resin and acetylene.
2,It is an excellent organic solvent. It is used as a solvent for polyurethane, polyacrylonitrile and polyvinyl chloride, as well as As as an extractant, pharmaceutical and pesticide raw material for chlordimeform.
3,Dimethylformamide is not only an extremely versatile chemical raw material, but also an excellent solvent with a wide range of uses. It can be used for wet spinning of polyacrylonitrile fiber and other synthetic fibers, synthesis of polyurethane, plastic film, paint removal agent, and some pigments with low solubility, give the pigment the character of a dye. The Dimethylformamide can be used for aromatics extraction and for the recovery of Butadiene from C _ 4 and C _ 5 fractions, as well as for the recovery of isoprene from paraffin. It has good selectivity for the solubility of isophthalic acid and terephthalic acid: the solubility of isophthalic acid in Dimethylformamide is greater than that of terephthalic acid, solvent extraction in Dimethylformamide or partial crystallization, the two can be separated. In petrochemistry, Dimethylformamide is used as a gas absorbent to separate and refine gases. In organic reactions, Dimethylformamide are widely used not only as solvents but also as important intermediates in organic synthesis. The pesticide industry can be used to produce chlordimeform; In the pharmaceutical industry, it can be used to synthesize sulfadiazine, Doxycycline, cortisone, vitamin B6, iodic glycoside, vermicullin, thiopyrimidine, n-formylsarcomycin, antineoplastic acid, methoxyaromatic mustard, biannitrogen mustard, cyclohexanitrosourea, furosemide, tranexamic acid, pemetasone, medroxyprogesterone, Doxycycline, chlorpheniramine, etc. . The Dimethylformamide is used as a catalyst in hydrogenation, dehydrogenation, dehydration and dehalogenation reactions, resulting in lower reaction temperature and higher purity of the product.
4,Reagent for non-aqueous solution titration, solvent of vinyl resin and acetylene, organic synthesis, photometric determination, gas chromatography stationary liquid (maximum temperature 50 ° C, solvent is methanol) , separation and analysis of C2-C5 hydrocarbons, and can separate N-, isobutene-[1] and cis-, trans-butene-[2] . Analysis of pesticide residues. Organic synthesis. Synthesis of peptides. For the photographic industry.
Emergency measures
Skin contact: Immediately remove contaminated clothing and rinse with plenty of flowing water for 20-30 minutes. If you feel uncomfortable, seek medical attention. If you feel uncomfortable, seek medical attention.
Eye contact: Immediately lift the eyelids and thoroughly rinse with plenty of flowing water or saline solution for 10-15 minutes. If you feel uncomfortable, seek medical attention.
Inhalation: Quickly leave the scene and move to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. Respiratory and cardiac arrest, immediately perform cardiopulmonary resuscitation. Seek medical attention.
Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.
Fire protection measures
Hazardous characteristics: Flammable, with the risk of combustion and explosion when exposed to open flames, high heat, or contact with oxidants. It can react violently with concentrated sulfuric acid and fuming nitric acid, and even explode. Strong reactions can occur with halides such as carbon tetrachloride.
Harmful combustion products: carbon monoxide, nitrogen oxides.
Extinguishing method: use foggy water, insoluble foam, dry powder, carbon dioxide and sand to extinguish the fire.
Firefighting precautions and measures: Firefighters must wear gas masks and full body firefighting suits, and extinguish fires in the upwind direction. Try to move the container from the fire scene to an open area as much as possible. Spray water to keep the fire container cool until the fire is extinguished. If the container in the fire has changed color or produced sound from the safety relief device, it must be evacuated immediately.
Emergency response to leakage
Eliminate all ignition sources. Designate a warning zone based on the impact area of liquid flow and vapor diffusion, and evacuate unrelated personnel from crosswind and upwind directions to a safe zone. It is recommended that emergency personnel wear positive pressure self-contained breathing apparatus and anti-static clothing. All equipment used during homework should be grounded. Do not come into contact with or cross over leaked materials. Cut off the leakage source as much as possible. Prevent leakage from entering water bodies, sewers, basements, or enclosed spaces.
Minor leakage: Absorb with sand or other non combustible materials. Collect absorbent materials using clean, non sparking tools.
Massive leakage: Construct embankments or dig pits to contain it. Absorb a large amount of liquid with fly ash or lime powder. Cover with insoluble foam to reduce evaporation. Spray mist can reduce evaporation, but it cannot reduce the flammability of leaked materials in confined spaces. Transfer to a tanker or dedicated collector using an explosion-proof pump.
