Chemical property
Alkaline, 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
