Abstract
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.
