HCID 71124,4'-Dihydroxybiphenyl

Procedure

The same reaction and post-treatment as described in Example 1 were carried out, except that 75.7 g (0.20 mole) of the phenol adduct of 4,4-bis(4-hydroxyphenyl)cyclohexanol was used in place of 56.9 g (0.20 mole) of 4,4-bis(4-hydroxyphenyl)cyclohexanol. 4,4'-Bisphenol was obtained as white crystals in a yield of 33.8 g. The product had a purity of 98.1% based on liquid chromatography and a p-phenylphenol content of 1.2%.
