摘要： 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.

摘要： The invention is a process to recover 4-phenoxybiphenyl from a phenoxybiphenyl mixture which includes at least 30% by weight of 4-phenoxybiphenyl, the balance being 2-phenoxybiphenyl, 3-phenoxybiphenyl and a minor amount of other compounds. The process involves recrystallizing 4-phenoxybiphenyl as a solid in a single recrystallization step from a solution formed from the mixture and an alcohol solvent. The recovered solid has a 4-phenoxybiphenyl content of at least about 85% by weight of recovered solid and a yield of at least 40% based on the amount of 4-phenoxybiphenyl in the mixture.
