Patent number: 9586898Abstract: In a process for oxidizing a feed comprising cyclohexylbenzene, the feed is contacted with oxygen and an oxidation catalyst in a plurality of reaction zones connected in series, the contacting being conducted under conditions being effective to oxidize part of the cyclohexylbenzene in the feed to cyclohexylbenzene hydroperoxide in each reaction zone. At least one of the plurality of reaction zones has a reaction condition that is different from another of the plurality of reaction zones. The different reaction conditions may include one or more of (a) a progressively decreasing temperature and (b) a progressively increasing oxidation catalyst concentration as the feed flows from one reaction zone to subsequent reaction zones in the series.Type: GrantFiled: August 16, 2011Date of Patent: March 7, 2017Assignee: ExxonMobil Chemical Patents Inc.Inventors: Jihad Mohammed Dakka, Francisco Manuel Benitez, Bryan Amrutlal Patel, Edmund John Mozeleski

Patent number: 9169181Abstract: In a process for producing cyclohexylbenzene hydroperoxide, cyclohexylbenzene is contacted with oxygen to produce a reaction product comprising cyclohexylbenzene hydroperoxide and unreacted cyclohexylbenzene. The reaction product is then maintained under conditions such that crystals of cyclohexylbenzene hydroperoxide form and separate from the reaction product. The cyclohexylbenzene hydroperoxide crystals are then recovered from the reaction product.Type: GrantFiled: November 28, 2011Date of Patent: October 27, 2015Assignee: ExxonMobil Chemical Patents Inc.Inventors: Kun Wang, Edmund John Mozeleski, Jihad Mohammed Dakka
