Abstract
A process for the formation of 2,6-diphenylphenol involving the autocondensation of cyclohexanone with itself to form a mixture of cyclic ketones containing a tricyclic ketone fraction and the dehydrogenation of the tricyclic ketone fraction to form 2,6-diphenylphenol. The process is characterized by reaction conditions permitting the formation of 2,6-diphenylphenol on a commercial scale that is free of impurities and suitable for many new applications requiring high purity as synthesis of drugs, plastics and the like.
