Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2. Consisting of a phenyl group ( −C 6 H 5 ) attached to an amino group ( −NH 2 ), aniline is the simplest aromatic amine .
Aniline absorbs in the K (220 - 250 nm) and the B (250 - 290 nm) bands exhibited by benzenoid compounds. The K and B bands arise from π to π* transitions as a result of the a group containing multiple bond being attached to the benzene ring. When dissolved in ethanol, λ max for aniline is 230 nm, but in dilute aqueous acid λ max is 203 nm ...

A white solid, it is the chloride salt of anilinium, which is the conjugate acid of aniline, C 6 H 5 NH 2. Anilinium chloride is produced by treatment of aniline with hydrochloric acid. The cation consists of a phenyl ring attached to a tetrahedral ammonium center. The C-N bond elongates from 1.41 Å in aniline to 1.474 Å in anilinium. [2]
Fuchsine (sometimes spelled fuchsin) or rosaniline hydrochloride is a magenta dye with chemical formula C 20 H 19 N 3 ·HCl. [1] [2] There are other similar chemical formulations of products sold as fuchsine, and several dozen other synonyms of this molecule. [1] It becomes magenta when dissolved in water; as a solid, it forms dark green crystals.
2,4,6-Trichloroaniline + 3 HCl The preparation of 2,4,6-trichloroaniline Safety Occupational exposure to 2,4,6-trichloroaniline may occur through inhalation and dermal contact with this compound at workplaces where 2,4,6-trichloroaniline is produced or used (SRC). The general population may be exposed to 2,4,6-trichloroaniline via drinking water and dermal contact with this compound in ...
Route 2: Substituted formamide + aniline: Figure 2; Amitraz Synthesis Route 2. The first step of this synthesis route to an N-arylformamidine as amitraz is the reaction of a substituted formamide, usually a dialkylformamide, with an aniline. [6] To gain amitraz N-methyl formamide and 2,4 dimethyl aniline hydrochloride can be used
Diphenylamine is produced by the thermal deamination of aniline over oxide catalysts: 2 C 6 H 5 NH 2 → (C 6 H 5) 2 NH + NH 3. It is a weak base, with a K b of 10 −14. With strong acids, it forms salts. For example, treatment with sulfuric acid gives the bisulfate [(C 6 H 5) 2 NH 2] + [HSO 4] − as a white or yellowish powder with m.p. 123 ...
