GENERAL DESCRIPTION & APPLICATIONS

Biphenyl (also called Diphenyl, but exactly one of two compounds. The other is o-phenylphenol, used to prevent the growth of moulds ) is an aromatic hydrocarbon; molecule structure is composed of two six-sided carbon rings connected at one carbon site on each ring. Pure biphenyl is a toxic colourless crystalline solid with a pleasant odour; melting point 70 C, boiling point 255 C, which gives plates or monoclinic prismatic crystals; it is insoluble in water but soluble in ordinary organic solvents. It is directly used in the preservation of citrus fruits  as a fungistat in transportation containers. It is a raw material for polychlorinated diphenyls (PCB) in which chlorine replaces hydrogen in biphenyls. There are 209 chlorinated isomers of biphenyl theoretically. But PCBs are referred to the biphenyl compounds with one to ten chlorine substitutions. PCBs are used heat-transfer agents and as electric insulators that block the flow of electric current across in electrical equipments. They are known as environmental pollution materials which are accumulated in animal tissues and cause toxic effects including carcinogenesis. Biphenyl is used as an intermediate for the production of a wide range of organic compounds (e.g. emulsifiers, optical brighteners, crop protection products, plastics), as a heat transfer medium alone or with diphenyl ether in heating fluids, as a dyestuff carrier for textiles and copying paper and as a solvent in pharmaceutical production. Aminodiphenyls are used as rubber antioxidants and intermediates for the synthesis of organic compounds ( azo dyes and pharmaceuticals). Biphenyl derivatives are used as an intermediate for the synthesis of organic compounds including pharmaceuticals, antifungal agents, optical brightening agents and dyes. Biphenyl compounds also used in luminescence chemistry, spectrophotometric analysis, molecular chemistry, and as a stating material for organometallic-complexes.  4,4'-Bis(chloromethyl)-1,1'-biphenyl is used as an intermediate for optical brightening agents and pharmaceuticals.
