  • Can anilines be made from petrochemicals?
  • These are all high-value commercial products, so finding versatile ways to make anilines from abundant chemicals is of great interest. Simple anilines are generally derived from benzene, toluene and xylenes (BTX) — petrochemicals available at low cost in bulk quantities.
  • Can aniline be used in dye production?
  • Dependency on Crude Oil: As aniline is derived from benzene, a crude oil product, its production is subject to the price volatility and availability of crude oil. Despite these challenges, there are strategies to mitigate them and ensure the successful application of aniline in dye production:
  • How is aniline produced?
  • Industrial aniline production involves two steps. First, benzene is nitrated with a concentrated mixture of nitric acid and sulfuric acid at 50 to 60 °C to yield nitrobenzene. The nitrobenzene is then hydrogenated (typically at 200–300 °C) in the presence of metal catalysts: Approximately 4B kg are produced annually.
  • What are the different types of aniline oil?
  • In commerce, three brands of aniline are distinguished: aniline oil for blue, which is pure aniline; aniline oil for red, a mixture of equimolecular quantities of aniline and ortho- and para-toluidines; and aniline oil for safranine, which contains aniline and ortho- toluidine and is obtained from the distillate (échappés) of the fuchsine fusion.
