PHENOL AND CYCLOHEXANONE MIXTURES

摘要

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 cleavage reaction product may comprise 1 wt% - 30 wt% phenol; 1 wt% - 30 wt% cyclohexanone; and 0.1 wt% to 10 wt% of at least one of water, bicyclohexane, cyclohexenylbenzene, methylcyclopentanone, 1 -phenylhexan- 1 -one, cyclohexyldione, cyclohexanol, cyclohexenone, hydroxycyclohexanone, benzoic acid, phenyl cyclohexanol, hexanal and 1-phenyl-6-hydroxyhexan-l-one, wherein the wt%s are based upon the total weight of the mixture.
