ECHEMI Editorial Reference

Biphenyl has a pungent odor, reminiscent of rose on dilution. white crystals 1,1’-Biphenyl is a clear colorless liquid with a pleasant odor and stable organic compound. It is combustible at high temperatures, producing carbon dioxide and water when combustion is complete. Partial combustion produces carbon monoxide, smoke, soot, and low molecular weight hydrocarbons. It is used extensively in the production of heat-transfer fl uids, for example, as an intermediate for polychlorinated biphenyl
