    • In a process for producing phenol and cyclohexanone, a feed comprising cyclohexylbenzene is oxidized to produce an oxidation reaction product comprising cyclohexyl-1 -phenyl- 1 -hydroperoxide. At least a portion of the oxidation reaction product is then cleaved to produce a cleavage reaction product comprising phenol, cyclohexanone, and at least one contaminant. At least a portion of the cleavage reaction product is contacted with an acidic material to convert at least a portion of the at least one contaminant to a converted contaminant and thereby produce a modified reaction product. The composition comprising cyclohexylbenzene may have at least 10 wt% of cyclohexylbenzene; 1 wppm to 1 wt% of bicyclohexane; 1 wppm to 1 wt% of biphenyl; and 1 wppm to 2 wt% of methylcyclopentylbenzene, wherein the wt%s and wppms are based upon total weight of the composition.
    • 在生产苯酚和环己酮的方法中,包含环己基苯的进料被氧化以产生包含环己基-1-苯基-1-氢过氧化物的氧化反应产物。 然后切割至少一部分氧化反应产物以产生包含苯酚,环己酮和至少一种污染物的裂解反应产物。 至少一部分裂解反应产物与酸性物质接触以将至少一种污染物的至少一部分转化为转化的污染物,由此产生改性的反应产物。 包含环己基苯的组合物可具有至少10重量%的环己基苯; 1重量ppm至1重量%的双环己烷; 1重量ppm至1重量%的联苯; 和1wppm到2wt%的甲基环戊基苯,其中wt%s和wppms基于组合物的总重量。
