Description
Aniline appears as a yellowish to brownish oily liquid with a musty fishy odor. Melting point -6°C; boiling point 184°C; flash point 158°F. Denser than water (8.5 lb / gal) and slightly soluble in water. Vapors heavier than air. Toxic by skin absorption and inhalation. Produces toxic oxides of nitrogen during combustion. Used to manufacture other chemicals, especially dyes, photographic chemicals, agricultural chemicals and others.;Liquid; PelletsLargeCrystals;Liquid;COLOURLESS OILY LIQUID WITH CHARACTERISTIC ODOUR. TURNS BROWN ON EXPOSURE TO AIR OR LIGHT.;Colorless to brown, oily liquid with an aromatic amine-like odor.;Colorless to brown, oily liquid with an aromatic amine-like odor.
