Abstract:
1. A process for producing phenol, the process comprising: (a) cleaving cyclohexylbenzene hydroperoxide to produce a cleavage effluent stream comprising phenol and cyclohexanone in a weight ratio of phenol to cyclohexanone of about 0.7:1 to about 1.5:1; (b) fractionating at least a portion of the cleavage effluent stream to produce (b-1) recovering the first fraction as a cyclohexanone product; and (c) contacting at least a portion of the second fraction with a dehydrogenation catalyst in a dehydrogenation reaction zone under dehydrogenation conditions effective to convert at least a portion of the cyclohexanone in said portion of the second fraction into phenol and cyclohexanol.
