n,n-dimethylformamide usage and synthesis |
chemical properties | clear colorless liquid |
usage | solvent for many hydrophobic organic compounds. |
general description | a water-white liquid with a faint fishy odor. flash point 136°f. slightly less dense than water. vapors heavier than air. toxic by inhalation or skin absorption. may irritate eyes. |
air & water reactions | flammable. water soluble. |
reactivity profile | n,n-dimethylformamide may react violently with a broad range of chemicals, e.g.: alkaline metals (sodium, potassium), azides, hydrides (sodium borohydride, lithium aluminum hydride), bromine, chlorine, carbon tetrachloride, hexachlorocyclohexane, phosphorus pentaoxide, triethylaluminum, magnesium nitrate, organic nitrates. forms explosive mixtures with lithium azide [bretherick, 5th ed., 1995, p. 453]. oxidation by chromium trioxide or potassium permanganate may lead to explosion [pal b. c. et al., chem. eng. news, 1981, 59, p. 47]. |
health hazard | irritation of eyes, skin and nose. may cause nausea. |
