• benzene
  • Biphenyl is produced industrially as a byproduct of the dealkylation of toluene to produce benzene: C6H5CH3 + C6H6 → C6H5−C6H5 + CH4 The other principal route is by the oxidative dehydrogenation of benzene: 2 C6H6 + ​1⁄2 O2 → C6H5−C6H5 + H2O Annually 40,000,000 kg are produced by these routes.

  • hydrogen
  • Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl. (wikipedia.org)
  • undergo
  • This mixture is stable to 400 °C. Biphenyl does undergo sulfonation followed by base hydrolysis produces p-hydroxybiphenyl and p,p′-dihydroxybiphenyl, which are useful fungicides. (wikipedia.org)
  • compounds
  • Biphenyl is also an intermediate for the production of a host of other organic compounds such as emulsifiers, optical brighteners, crop protection products, and plastics. (wikipedia.org)
