Abstract
In a process for oxidizing cyclohexylbenzene, a composition comprising cyclohexylbenzene is contacted with oxygen in at least one oxidation zone under oxidation conditions sufficient to produce at least some (i) cyclohexylbenzene hydroperoxide; (ii) a first byproduct; and (iii) a second byproduct in an effluent. A ratio β is determined according to the following formula:
