White or with yellow crystalline flake, it has unique aroma. Insoluble in water, acid and alkali, soluble in alcohol, ether, benzene etc organic solvents. Biphenyl have high thermal stability and low vapor pressure, for a long time, often alone or with diphenyl ether etc after mixing as heat body use. By biphenyl and three biphenyl components, such as the mountains of wax (including biphenyl 13%, three biphenyl 61%) can effectively absorb radiation, can be used as a nuclear power plant body heat. And three biphenyl (1573 - [4]) is exactly benzene pyrolysis of biphenyl when by-products, according to different reaction conditions, reaction products of biphenyl and three biphenyl proportion within the scope of certain change, usually, biphenyl: three biphenyl = 7 - eight-to-one. Biphenyl is also used for dyeing carrier, its derivatives ethyl biphenyl and diethyl biphenyl and three ethyl biphenyl can serve as a senior solvents, used pressure-sensitive carbon dyestuff solvent. But for phenylphenol derivatives biphenyl, also is mainly used to produce resin in pressure-sensitive carbon production as colour-display reagent, couplers.experiments of microcapsule material, also can be used in the manufacture of special coatings. Biphenyl can be used as impregnant, citrus wrapping paper also citrus plant some disease treatment. Chlorinated biphenyl is chlorinated rubber and vinyl plasticizing of polymer. Biphenyl is rodenticide rat duke and bromine rat spiritual intermediates, and it for good effect of organic vehicle. Engineering plastic poly sulphone raw material, manufacturing trimethoxysilane biphenyl and five biphenyls (and heat carrier, preservative, making dye, etc. Fungicide. Used for grapefruit, orange, lemon and other citrus fresh fruit epidermis mouldproof. Engineering plastic poly sulphone raw material, manufacturing trimethoxysilane biphenyl and five biphenyls (and heat carrier, preservative, making dye, etc. General use macerate crosses the product prayer-book put a container, in the top and bottom of the storage and transport process biphenyl sublimation, adsorption on peel, up anti-mold action. The preparation method based on benzene as raw materials, via dehydrogenation thermal cracking.
