Procedure

In the production of 3,3',5,5'-tetra-t-butylbiphenol, which is an intermediate of 4,4'-biphenol, from 2,6-di-t-butylphenol as a starting material, the above second process for producing 3,3',5,5'-tetra-t-butylbiphenol according to the present invention enables obtaining 3,3',5,5'-tetra-t-butylbiphenol in high yield with the full utilization of 2,6-di-t-butylphenol charged in the reaction vessel without detriment to the selectivity of 3,3',5,5'-tetra-t-butylbiphenol.
