Uses and applications
What the substance is used for, by industry and function
Manufacture dyes, medicinals, resins, varnishes, perfumes, shoe blacks, vulcanizing rubber, as solvent. Hydrochloride used in manufature of intermediates, aniline black and other dyes, in dyeing fabrics or wood black.
Rubber accelerators and antioxidants, dyes and intermediates, photographic chemicals (hydroquinone), isocyanates for urethane foams, pharmaceuticals, explosives, petroleum refining, diphenylamine, phenolics, herbicides, and fungicides.
As a stable, although small outlet, aniline is mainly used for preparation of analgesics, antipyretics, antiallergics, and vitamins.
Aniline is predominantly used as a chemical intermediate for the dye, agricultural, polymer, and rubber industries. It is also used as a solvent, and has been used as an antiknock compound for gasolines.
Industrial uses: Antioxidant, Processing aids not otherwise specified, Monomers, Lubricating agent, Pigment, Intermediate, Brightener.
Consumer uses: Pigment.

How it is made
Nitrobenzene is hydrogenated to aniline, usually in more than 99% yield, using fixed-bed or fluidized-bed vapor-phase processes. The most effective catalysts for the gas-phase hydrogenation of nitrobenzene seem to be copper or palladium on activated carbon or an oxidic support, in combination with other metals (Pb, V, P, Cr) as modifiers or promoters in order to achieve high activity and selectivity.
The industrial aniline processes of ICI and DuPont involve hydrogenation (of nitrobenzene) in the liquid phase. Liquid-phase hydrogenation processes are operated at 90-200 °C and 100-600 kPa.

The liquid phase reaction may be carried out in slurry or in fluidized-bed reactors. Conversion of nitrobenzene is normally complete after a single reactor pass with yields of 98 to 99%.
In the commercial phenol route developed by Halcon, phenol is aminated in the vapor phase using ammonia in the presence of a silica-alumina catalyst. ... The reaction is mildly exothermic (H = - 8.4 kJ/mol) and reversible, so high conversion is obtained only by the use of excess ammonia (mole ratio of 20:1) and a low reaction temperature, which also reduces the dissociation of ammonia. Byproduct impurities include diphenylamine, triphenylamine and carbazole. Their formation is also inhibited by the use of excess ammonia. Yields based on phenol and ammonia are >/= 96% and 80%, respectively.
