Did you know?
Lacking functional groups, biphenyl is fairly non-reactive, which is the basis of its main application. In the laboratory, biphenyl is mainly used as a heat transfer agent as a eutectic mixture with diphenyl ether. This mixture is stable to 400 °C. Biphenyl does undergo sulfonation which, followed by base hydrolysis, produces p-hydroxybiphenyl and p,p′-dihydroxybiphenyl, which are useful fungicides. In other substitution re… WebConductivity measurements carried out on samples with varying compositions of lithium, biphenyl (β), and THF reveal the highest conductivity of 12.0 mS/cm is achieved with …
