Abstract
In a process for producing phenol, a feed comprising cyclohexylbenzene hydroperoxide is contacted with a cleavage catalyst comprising a fluorinated acidic resin under cleavage conditions effective to convert at least a portion of the cyclohexylbenzene hydroperoxide into phenol and cyclohexanone.
Claims25
A process for producing phenol, the process comprising:
- (a) contacting a feed comprising cyclohexylbenzene hydroperoxide with a cleavage catalyst comprising a halogenated acidic resin under cleavage conditions effective to convert at least a portion of said cyclohexylbenzene hydroperoxide into phenol and cyclohexanone.
A process for producing phenol, the process comprising:
- (a) contacting cyclohexylbenzene with an oxygen-containing compound in the presence of an oxidation catalyst under oxidation conditions effective to produce an oxidation product comprising cyclohexylbenzene hydroperoxide;
- and
- (b) contacting at least a portion of said oxidation product comprising cyclohexylbenzene hydroperoxide with a cleavage catalyst comprising a fluorinated acidic resin under cleavage conditions effective to convert at least a portion of said cyclohexylbenzene hydroperoxide into phenol and cyclohexanone.
A process for producing phenol, the process comprising:
- (a) hydroalkylating benzene with hydrogen in the presence of a hydroalkylation catalyst under conditions effective to produce a hydroalkylation reaction product comprising cyclohexylbenzene;
- (b) separating cyclohexylbenzene from said hydroalkylation reaction product;
- (c) contacting at least a portion of said cyclohexylbenzene from the separating step (b) with an oxygen-containing compound in the presence of an oxidation catalyst under oxidation conditions effective to produce an oxidation product comprising cyclohexylbenzene hydroperoxide;
- and
- (d) contacting at least a portion of said oxidation product comprising cyclohexylbenzene hydroperoxide with a cleavage catalyst comprising a fluorinated acidic resin under cleavage conditions effective to convert at least a portion of said cyclohexylbenzene hydroperoxide into phenol and cyclohexanone.
