Antioxidant antioxidants for rubber and plastics. Dye intermediates or petroleum products stabilizer.
製法・合成法
調製方法
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.
純化方法
Recrystallise the biphenol from aqueous EtOH preferably under N2 to avoid oxidation to the extended qiunone. It is characterized as the dimethyl derivative (4,4’-dimethoxybiphenyl) from which it is prepared by demethylation. The dimethoxy derivative has m 176.5-177o (from AcOH, EtOH, hexane or *C6H6) and sublimes in vacuo.
