    Abstract: 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.

    Abstract translation: 在制备联苯化合物的方法中，C n芳族烃可以被加氢烷基化以得到C 2n环烷基芳族化合物和副产物C n饱和环状烃。 将C2n环烷基芳族化合物脱氢以提供联苯化合物。 Cn饱和环状烃也可以脱氢回到相应的C n芳族烃，其可以再循环以提供额外的进料。 虽然中间体C2n环烷基芳族化合物和副产物Cn饱和环状烃都应脱氢，但Cn饱和环状烃的至少部分脱氢应在不存在C2n或更高级烃的情况下进行。 因此，副产物Cn饱和环状烃的脱氢应至少部分地与C2n环烷基芳族化合物的脱氢分开发生。

    Abstract: In a process for producing phenol and/or cyclohexanone, cyclohexylbenzene is contacted with an oxygen-containing gas under conditions effective to produce an oxidation effluent containing cyclohexylbenzene hydroperoxide. At least a portion of the oxidation effluent containing cyclohexylbenzene hydroperoxide is then contacted with a cleavage catalyst under conditions effective to produce a cleavage effluent containing phenol and cyclohexanone. At least one of the oxidation effluent and the cleavage effluent contains a by-product comprising a mixture of isomers of phenylcyclohexanol and/or phenylcyclohexanone, in which the 2-phenyl isomer(s) is present in an amount less than 20% of the mixture. At least a portion of the at least one effluent containing the isomer mixture is contacted with a dehydration catalyst under conditions effective to convert at least a portion of the mixture to isomers of phenylcyclohexene, with very low ring rearrangement to produce 1-methylcyclopentenylbenzene and cyclopentenylmethylbenzene.

    Abstract: In a process for producing phenol, a mixture of cyclohexylbenzene with from 10 to 90 wt % of a solvent is contacted with oxygen in the presence of a catalyst and under conditions effective to oxidize at least a portion of the cyclohexylbenzene to cyclohexylbenzene hydroperoxide. The catalyst comprises a cyclic imide having an imide group of formula (I): wherein X represents an oxygen atom, a hydroxyl group, or an acyloxy group. At least a portion of the oxygen is dissolved in the mixture and the liquid phase molar ratio of cyclohexylbenzene to oxygen dissolved in the mixture is less than or equal to 20,000:1.
