2,2'-Biphenol

<p>2,2'-Biphenol</p>

<p>2,2'-Biphenol is a phenolic compound that is used in the synthesis of polymers. The thermal expansion coefficient of 2,2'-biphenol can be measured by DSC and found to be ˜6.5 × 10−4/°C. The UV absorption spectrum of 2,2'-biphenol shows three bands at wavelengths of 290 nm, 320 nm, and 370 nm. 2,2'-Biphenol has been shown to adsorb onto biological surfaces through an adsorption mechanism. It has been observed that this adsorption occurs via x-ray crystal structures and kinetic measurements have shown that the adsorption process is rate-limited by intramolecular hydrogen bonding between the protonated phenolic hydroxyl group and the aromatic ring. The activation energies for protonation and desorption have been determined to be ˜30 kJ/mol and ˜30 kJ/mol respectively. Ac</p>
