ABSTRACT:
A process for the preparation of dihydroxy polyphenyl compounds is disclosed which comprises the simultaneous steps of (a) contacting the corresponding diisoalkyl polyphenyl compound or an oxidation intermediate thereof with oxygen under reaction conditions sufficient to form a corresponding dihydroperoxyalkyl polyphenyl compound and (b) contacting the dihydroperoxyalkyl polyphenyl compound with an acid under reaction conditions sufficient to form the corresponding dihydroxy polyphenyl compound. In addition, the intermediate dihydroperoxyalkyl polyphenyl compound is a novel compound.
