    摘要: In a process for producing phenol and cyclohexanone, reaction components comprising cyclohexylbenzene hydroperoxide and an acid catalyst are supplied to a cleavage reaction zone, mixed under mixing conditions effective to combine the reaction components into a reaction mixture and at least part of the cyclohexylbenzene hydroperoxide in the reaction mixture is converted under cleavage conditions to into phenol and cyclohexanone; and a cleavage effluent is recovered from the cleavage reaction zone. The cleavage and mixing conditions are controlled such that the ratio
    t
    R /
    t
    M is at least 10, where
    t
    R is the half-life of cyclohexylbenzene hydroperoxide under the cleavage conditions and
    t
    M is the time required after injection of a tracer material into the reaction mixture under the mixing conditions for at least 95% by volume of the entire reaction mixture to attain at least 95% of the volume-averaged tracer material concentration.

    摘要: 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 compound comprising an atom not being carbon, hydrogen or oxygen, which is separated from the cleavage effluent and/or the neutralized product thereof to leave a cleavage fraction lean in the compound comprising an atom not being carbon, hydrogen or oxygen 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.
