Abstract
A process for producing 4,4'-dihydroxydiphenyls is disclosed, which comprises dimerizing alkylphenols in an aqueous solution of pH 7 to 12 containing a surfactant in the presence of an oxidizing agent, wherein the dimerization is conducted in the presence of a copper compound and a basic boron compound or a mixture of a basic substance and a boron compound. According to this process, the desired 4,4'-dihydroxydiphenyls can be easily obtained in high yield.
