What is Biphenyl?

Plain description, key identifiers and synonyms

Biphenyl is a benzenoid aromatic compound that consists of two benzene rings connected by a single covalent bond. Biphenyl occurs naturally in coal tar, crude oil, and natural gas. Formerly used as a fungicide for citrus crops. It has a role as an antimicrobial food preservative and an antifungal agrochemical. It is a member of benzenes, a member of biphenyls and an aromatic fungicide.

Biphenyl is an organic compound consisting of two phenyl groups.

How it is made

By heating bromobenzene and sodium, with subsequent distillation. (As well as) by slowly passing benzene through a red-hot iron tube

/Produced/ by passing benzene vapors over ferroso-ferric or lead oxide at high temp, in small quantities.

Suppliers recover biphenyl from high boiler fractions that accompany the hydrodealkylation of toluene to benzene. Numerous hydrodealkylation processes have been developed. Most have the common feature that toluene or other alkylbenzene plus hydrogen is passed under pressure through a tubular reactor at high temperature. Methane and benzene are the principal products formed. Dealkylation conditions are sufficiently severe to cause some dehydrocondensation of benzene and toluene molecules. Approximately 1 kg of biphenyl per 100 kg of benzene is produced.
