  Described herein is a process for producing phenol in which (a) benzene and hydrogen are contacted with a hydroalkylation catalyst under hydroalkylation conditions to produce cyclohexylbenzene; (b) the cyclohexylbenzene is contacted with an oxidation catalyst under oxidation conditions to produce cyclohexylbenzene hydroperoxide; (c) the cyclohexylbenzene hydroperoxide is contacted with a cleavage catalyst under cleavage conditions to produce a cleavage effluent comprising phenol and cyclohexanone; (d) the cyclohexanone is contacted with a dehydrogenation catalyst under dehydrogenation conditions to produce a dehydrogenation effluent having at least a portion of the cyclohexanone and a first contaminant; and (e) the first contaminant is contacted with an acidic material under contaminant treatment conditions to convert at least a portion of the first contaminant into a converted first contaminant. Phenol compositions made from the above-described process are also described herein.

  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.
