Abstract

In a process for producing phenol and/or cyclohexanone, cyclohexylbenzene is contacted with an oxygen-containing gas to produce an oxidation effluent containing cyclohexylbenzene hydroperoxide. At least a portion of the cyclohexylbenzene hydroperoxide is then contacted with a cleavage catalyst to produce a cleavage effluent containing phenol and cyclohexanone and by-products including phenylcyclohexanol. The cleavage effluent or a neutralized product thereof also comprises at least one heteroatom-containing compound, which is separated from the cleavage effluent and/or the neutralized product thereof to leave a cleavage fraction lean in the heteroatom-containing compound and containing at least a portion of the phenylcyclohexanol. At least a portion of the phenylcyclohexanol is then contacted with a dehydration catalyst comprising a molecular sieve of the MCM-22 type to convert at least a portion of the phenylcyclohexanol to phenylcyclohexene.
