Abstract
In a process for producing phenol, cyclohexylbenzene is contacted with an oxygen-containing compound in the presence of an oxidation catalyst comprising a cyclic imide under oxidation conditions effective to produce a product comprising cyclohexylbenzene hydroperoxide and unreacted cyclic imide catalyst. Without removing all the unreacted cyclic imide catalyst, at least a portion of the product is contacted with an acidic molecular sieve under conditions effective to adsorb at least a portion of the unreacted cyclic imide and to convert at least part of the cyclohexylbenzene hydroperoxide in the product portion into phenol and cyclohexanone.
