    摘要: A process for making phenol and/or cyclohexanone comprises: (A) oxidizing a cyclohexylbenzene feed to obtain an oxidation product comprising cyclohexylbenzene, cyclohexyl-1-phenyl-1-hydroperoxide and phenol; (B) separating at least a portion of the oxidation product to obtain a first fraction comprising cyclohexyl-1-phenyl-1-hydroperoxide and a second fraction comprising cyclohexylbenzene and phenol; (C) removing at least a portion of the phenol from at least a portion of the second fraction to obtain a third fraction; (D) recycling at least a portion of the cyclohexylbenzene in the third fraction to the oxidizing step (A); and (E) contacting at least a portion of the cyclohexyl-1-phenyl-1-hydroperoxide in the first fraction with an acid catalyst in a cleavage reactor under cleavage conditions to obtain a cleavage product comprising phenol and cyclohexanone.

    摘要: In a process for producing cyclohexanone, cyclohexylbenzene is oxidized to produce cyclohexylbenzene hydroperoxide and then the resultant cyclohexylbenzene hydroperoxide is cleaved to produce an effluent stream comprising phenol and cyclohexanone. At least a portion of the effluent stream is then fed to at least one hydrogenation reaction zone, where the effluent stream portion is contacted with hydrogen in the presence of a hydrogenation catalyst under conditions effective to convert at least part of the phenol in the effluent portion into cyclohexanone.

    摘要: A process for producing phenol and methyl ethyl ketone comprises contacting benzene and a C4 alkylating agent under alkylation conditions and in the presence of an alkylation catalyst comprising at least one molecular sieve of the MCM-22 family to produce an alkylation effluent comprising secbutylbenzene; wherein the contacting is conducted in a plurality of reaction zones and the C4 alkylating agent is supplied to each of the reaction zones. A secbutylbenzene fraction is recovered from the alkylation effluent and comprises at least 95 wt% sec-butylbenzene, less than 100 wt ppm of C8+ olefins, and less than 0.5 wt% of isobutylbenzene and tert-butylbenzene. The sec-butylbenzene fraction is then oxidized to produce sec-butylbenzene hydroperoxide and the hydroperoxide is cleaved to produce phenol and methyl ethyl ketone.

    摘要: In a process for producing biphenyl compounds, a Cn aromatic hydrocarbon may be hydroalkylated to give C2n cycloalkylaromatic compounds and byproduct Cn saturated cyclic hydrocarbons. The C2n cycloalkylaromatic compounds are dehydrogenated to provide the biphenyl compounds. The Cn saturated cyclic hydrocarbons may also be dehydrogenated back to the corresponding Cn aromatic hydrocarbon, which may be recycled to provide additional feed. Although both the intermediate C2n cycloalkylaromatic compounds and the byproduct Cn saturated cyclic hydrocarbons should be dehydrogenated, at least part of the dehydrogenation of the Cn saturated cyclic hydrocarbons should take place in the absence of C2n or greater hydrocarbons. Thus, dehydrogenation of the byproduct Cn saturated cyclic hydrocarbons should take place at least in part separately from dehydrogenation of the C2n cycloalkylaromatic compounds.
