3. Product Details of 4,4'-Biphenol
4,4'-Biphenol can be synthesized in excellent yields by debutylation of 3,3',5,5'-tetra-tert-butyl-4,4'-dihydroxybiphenyl. Other production processes are the alkaline fusion of 4,4'-biphenyldisulfonic acid, the boil down of benzidinebisdiazonium salts, and the decarboxylation of 4,4'-dihydroxybiphenyl-2-carboxylic acid. Symmetrically alkylated 4,4'-dihydroxybiphenyls such as 4,4'-dihydroxy-2,2',3,3',5,5',6,6'-hexamethylbiphenyl are preferably obtained by the oxidative coupling of the corresponding substituted monophenols. Here, diphenoquinones are generally formed in the first step which must be reduced. Phenol itself always gives isomeric mixtures of dihydroxybiphenyls on coupling with various oxidants. These mixtures are also formed by alkaline fusion of 4,4'-dihydroxybiphenylsulfone.
