  • Patent number: 9586898
    Abstract: 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.

  • Patent number: 9169181
    Abstract: 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.

  • Patent number: 9029621
    Abstract: A process for oligomerizing isobutene comprises contacting a feedstock comprising isobutene with a catalyst comprising a MCM-22 family molecular sieve under conditions effective to oligomerize the isobutene, wherein said conditions including a temperature from about 45° C. to less than 140° C. The isobutene may be a component of a hydrocarbon feedstock containing at least one additional C4 alkene. In certain aspects, isobutene oligomers are separated from a first effluent of the oligomerization to produce a second effluent comprising at least one n-butene. The second effluent can be contacted with an alkylation catalyst to produce sec-butylbenzene.
