Product Description
Product introduction
N, N-Dimethylformamide; DMF; CAS: 68-12-2
Molecular formula C3-H7-N-O. Molecular weight 73.10.Dimethylformamide (DMF) is a transparent liquid that dissolves with water and most organic solvents. It is a common solvent for chemical reactions. Pure dimethylformamide is odorless, but industrial grade or metamorphic dimethylformamide is fishy, because it contains impurities in dimethylamine.
Characteristic and superiority
Dimethylformamide is made from formic acid and dimethylamine. Dimethylformamide is unstable (especially at high temperatures) in the presence of a strong base such as sodium hydroxide or a strong acid such as hydrochloric acid or sulfuric acid and is hydrolyzed to formic acid with dimethylamine.Physical and chemical properties: colorless, light ammonia smell of liquid.
Application
1. Determination of C2-C5 hydrocarbons by separation of non-aqueous solution titration reagents, solvent of vinyl resin and acetylene, organic synthesis, photometric determination, gas chromatographic fixation (maximum temperature of 50 ℃, solvent methanol), and separation of iso- ] And smooth, anti-butene. Analysis of Pesticide Residue. Organic Synthesis. Synthesis of Peptides. For photographic industry.
2. A very good use of excellent solvent and chemical raw materials. For a variety of polymers such as polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc. are excellent solvents. in addition to paint paint remover; acetylene selective absorption and separation and purification of butadiene; artificial leather production as a solvent; Used in the synthesis of pesticides; pharmaceutical industry can be used for the synthesis of i-pyrimidine, doxycycline, cortisone, vitamin B6, iodine, pinning net, thiopyrimidine, N-formyl lysoside, , Methoxy aromatic mustard, bian nitrogen mustard, cyclohexanone nitrosourea, furazolidazole, hemostatic ring acid, times the United States pine, a progesterone, gall bladder, chlorpheniramine and so on.
3. Used as solvent and organic modifier in liquid chromatography, extraction agent for thin layer chromatography and developing solvent, solvent of ethylene resin and acetylene, and solvent for non-aqueous solvent titration. And for organic synthesis.
