  • 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: 9365474
    Abstract: Disclosed herein are processes for producing phenol. The processes include oxidizing cyclohexylbenzene to produce an oxidation composition comprising cyclohexyl-1-phenyl-1-hydroperoxide. The cyclohexyl-1-phenyl-1-hydroperoxide in the oxidation composition may undergo a cleavage reaction to produce a cleavage reaction mixture comprising phenol, cyclohexanone and at least one contaminant. The cleavage reaction mixture may be contacted with a basic material to convert at least a portion of the contaminant to a converted contaminant, thereby producing a modified reaction mixture.

  • Patent number: 8884068
    Abstract: Disclosed herein is a process for producing phenol. The process includes oxidizing at least a portion of a feed comprising cyclohexylbenzene to produce an oxidation composition comprising cyclohexyl-1-phenyl-1-hydroperoxide. The oxidation composition may then be cleaved in the presence of an acid catalyst to produce a cleavage reaction mixture comprising the acid catalyst, phenol and cyclohexanone. At least a portion of the cleavage reaction mixture may be neutralized with a basic material to form a treated cleavage reaction mixture. In various embodiments, the cleavage reaction mixture contains 1 wt % to 30 wt % phenol, 1 wt % to 30 wt % cyclohexanone and a complexation product.

  • Patent number: 8568846
    Abstract: Provided are compositions, processes for making, and processes for using neoalkyl polyol esters and triglycerides as plasticizers. In one form, a neoalkylester triglyceride plasticizers can be produced by (i) drying a polyol feedstream; (ii) contacting in a reactor the dried polyol feedstream with a neoacid feedstream under effective temperature, pressure and time to form a neoalkylester plasticizer effluent stream, and (iii) purifying the neoalkylester plasticizer effluent stream to remove unreacted polyol and unreacted neoacid to form a neoalkylester plasticizer. Such plasticizers can be phthalate-free and provide outstanding properties including a suitable melting or pour point, glass transition temperature, low volatility, increased compatibility, increased hydrolytic stability, and excellent low temperature properties in a range of polymeric resins.
