description

Biphenyl is also called phenyl benzene, it is formed by two connected phenyl compounds, is white or colorless to light yellow crystal plate, industrial products is slightly yellow with special fragrance. The melting temperature is 69.2 ℃, boiling point is 69.2 ℃. Insoluble in water, but soluble in organic solvents. Commonly used for organic synthesis precursor, is one of the key components of the organic high temperature heating medium. Its derivatives include benzidine, diphenyl ether, eight bromine diphenyl ether, polychlorinated biphenyls, etc.

Natural biphenyl exists in coal tar, crude oil and natural gas, the mass fraction is 0.20% to 0.20% in coal tar, current preparation methods of biphenyl include coal tar extraction and chemical synthesis.
The chemical bond in the middle of biphenyls can rotate freely, but if there were bulky groups in the four orthos, restricts rotation and would produce resistance isomer. This type of compounds (such as BINAP) can be used as a chiral ligands. substituted biphenyl by Suzuki reaction and Ullmann coupling reactions.
Biphenyl is a kind of important organic raw materials, widely used in medicine, pesticides, dyes, liquid crystal materials, etc. Can be used in the synthesis of plasticizer, preservatives, can also be used to make fuel, engineering plastic and high energy fuel.
