"Biphenyl occurs naturally in coal tar, crude oil, and natural gas and can be isolated from these sources via distillation. It is produced industrially as a byproduct of the dealkylation of toluene to produce methane: The other principal route is by the oxidative dehydrogenation of benzene: Annually 40,000,000 kg are produced by these routes.
