Biphenyl Introduction
Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene or BP) is an organic compound that forms colorless crystals. 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.

Biphenyl is flammable. Be careful not to get close to the fire source. It is thermally stable and has similar chemical properties to benzene. It can undergo halogenation, nitration, sulfonation, hydrogenation and other reactions.
A derivative that reacts with bromine to form bromine. Nitrobiphenyl is formed during nitration.
Sulfonation reaction occurs with sulfuric acid in nitrobenzene to produce biphenyl-4-sulfonic acid and biphenyl-4,4 '- disulfonic acid.
It reacts with ozone in chloroform to form explosive tetraozone. The alkylation reaction produces 4-alkyl biphenyl and 4,4 '- dialkyl biphenyl. It reacts with acetyl chloride in the presence of aluminum trichloride to produce 4-acetylbiphenyl and 4,4 '- diacetyl biphenyl.
Biphenyl-4-carboxylic acid was synthesized by hydrolysis of Oxalyl Chloride with carbon disulfide as solvent. In the presence of zinc chloride, it reacts with formaldehyde and hydrochloric acid to produce chloromethylation reaction.

Application of Biphenyl
Biphenyl is an important organic raw material, which is widely used in medicine, pesticide, dye, liquid crystal materials and other fields. It can be used to synthesize plasticizers and preservatives, and can also be used to manufacture fuels, engineering plastics and high-energy fuels. Biphenyls are found in coal tar, crude oil and natural gas.
The preparation methods of biphenyl include chemical synthesis of biphenyl by pyrolysis of benzene and separation and extraction of biphenyl from various coal tar oil fractions. The mass fraction of biphenyl in coal tar is 0.20% - 0.40%. Coal tar extraction and chemical synthesis coexist. Biphenyl is combustible.
Biphenyl is used as heat exchanger and impregnator of fruit packaging paper. Biphenyl can be used in organic synthesis. Biphenyl is the raw material of engineering plastics polysulfone. It is used to prepare Trichlorobenzene and pentachlorophenyl. Biphenyl is used as heat carrier, preservative, dye and so on.
Biphenyl is used as a reference material for chromatographic analysis. Biphenyl is the intermediate of rodenticides rodenticide modek and bromadine, and it is an organic carrier with good performance.

In case of high temperature, open fire and oxidant, it is dangerous to burn. It should be stored in a cool and ventilated warehouse away from kindling and heat source. It should be stored separately from oxidants and strong acids. It should be loaded and unloaded gently to keep the package intact.
