Industrial Grade Organic Solvent N N-Dimethylformamide

Industrial Grade Organic Solvent N N-Dimethylformamide N N-DimethylformamideDetail Description: N N-Dimethylformamide Dimethylformamide(DMF)Is a transparent liquid, soluble in water and most organic solvents. N N-Dimethylformamide is a common chemical reaction solvent pure Dimethylformamide was no smell. But the Industrial grade or deterioration of the N N-Dimethylformamide have Anabaena taste. N N-Dimethylformamide contains dimethyl amine impurities.  The name is because it is a source of amide (amide acid) and dimethyl substituted derivatives. While the two methyl are located in the N (nitrogen) atoms.  N N-Dimethylformamide is a high Boiling point: the polar (hydrophilic) aprotic solvent, can promote the conduct of SN2 reaction mechanism. N N-Dimethylformamide Physicochemical Property: N N-Dimethlformamide is colorless,Light liquid ammonia odor . N N-Dimethlformamide Molecular formula:C3-H7-N-O. N N-Dimethlformamide Molecular weight73.10. Relative density0.9445(25°C). Melting point:-61°C Boiling point:152.8°C. Flash point:57.78°C.  Vapor density2.51. Vapor pressure:0.49kpa(3.7mmHg25°C). Ignition point:445°C. Refractive index1.42817. Solubility parameterδ=12.1.Vapor and air mixture explosion limit: 2.2~15.2 % . With water and usually organic solvents. In case of fire, heat can cause a fire explosion.  With concentrated sulfuric acid, fuming nitric acid reacts violently or even explode.
