C6H7N First-class Phenylamine

Physical propertyAppearance and properties: colorless or slightly yellow oily liquid with a strong odor.Melting point (c):-6.2Relative density (water =1):1.02Boiling point (c):184.4Relative vapor density (air =1):3.22Saturated vapor pressure (kPa):2.00 (77 C)Combustion heat (kJ/mol):3389.8Critical temperature (c):425.6Critical pressure (MPa):5.30Octanol / water partition coefficient of value: 0.94The refractive index of 1.5863Explosion upper limit% (V/V):11.0Explosion lower limit% (V/V):1.3Solubility: slightly soluble in water, soluble in ethanol, ether, benzene.Chemical propertyAlkaline, and hydrochloride combine to form hydrochloride, sulfate and sulfate synthesis. Halide, acetylation, nitriding. encounter fire, high fever combustible, burning flame will smoke. With acids, halogen, alcohols, amines have reacted strongly, will cause burning. Aniline is one of the most important amines. Mainly used in the manufacture of dyes, drugs, resin, but also can used as rubber vulcanization accelerator. It can also be used as a black dye. The derivatives of methyl orange can be used as an acid-base titration indicator
