실험 절차

A process for the preparation of 4,4'-biphenol which comprises reacting 4-hydroxycyclohexanone with phenol in the presence of an acid catalyst to give 4,4-bis(4-hydroxyphenyl)cyclohexanol of the formula (I) ##STR5## and successively subjecting 4,4-bis(4-hydroxyphenyl)cyclohexanol to decomposition and dehydrogenation reactions in the presence of a dehydrogenation catalyst.
