Procedure

A starting material which was a mixture of 3,3',5,5'-tetra-t-butyl-4,4'-diphenoquinone (1.0 g) and 2,6-di-t-butylphenol (1.0 g) was subjected to reaction at 180° C. for 1 hour in a nitrogen gas atmosphere using 10 ml of phenol as a solvent and 0.05 g of sulfuric acid as a catalyst. p,p'-biphenol was produced in an amount of 0.49 g (yield, 54.0%).
