WebWhy is biphenyl more soluble in diethyl ether than water? Biphenyl is nonpolar and not able to form bonds to water. What solvent (diethyl ether or water) would glucose be most … 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. Webbiphenyl, also called Diphenyl, an aromatic hydrocarbon, used alone or with diphenyl ether as a heat-transfer fluid; chemical formula, C 6 H 5 C 6 H 5. It may be isolated from coal tar; in the United States, it is manufactured on a large scale by the thermal dehydrogenation of benzene.
