Biphenyl refractive index
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… WebAug 1, 1971 · The 410 cm-1 The Banian spectrum of biphenyl and biphenyl-d^g 1297 line which almost certainly marks a fundamental appears to appreciably weaken the 330 cm"1 interval and depress it in energy when the molecule goes from the planar to the twisted configuration.
