    Abstract: Disclosed are novel processes for making cyclohexanone compositions, from a mixture comprising phenol, cyclohexanone, and cyclohexylbenzene. The process includes hydrogenation of a feed stream comprising phenol, cyclohexanone, and cyclohexylbenzene. The feed stream may be subjected to one or more pre-hydrogenation treatments, such as passing through one or more sorbents, addition of basic chemical agents, and/or addition of water, so as to improve catalyst activity, minimize undesired side reactions, and/or remove catalyst poisons from the feed stream. The feed stream may be provided to a hydrogenation reaction zone in the vapor phase, with periodic alterations to hydrogenation reaction conditions such that the feed is provided in mixed liquid and vapor phase in order to carry out liquid washing of a hydrogenation catalyst bed within the hydrogenation reaction zone.

    Abstract: A process for making phenol and/or cyclohexanone, the process comprising: (A) oxidizing a cyclohexylbenzene feed to obtain an oxidation product comprising cyclohexylbenzene, cyclohexylbenzene hydroperoxide and water; (B) removing at least a portion of the water from at least a portion of the oxidation product to obtain a cleavage feed; and (C) contacting at least a portion of the cyclohexylbenzene hydroperoxide in the cleavage feed with an acid catalyst in a cleavage reactor under cleavage conditions to obtain a cleavage product comprising phenol and cyclohexanone. The removing step may also comprises a step of removing a portion of the cyclohexylbenzene contained in the oxidation product. Water removal may be advantageously conducted in a water flashing drum before a cyclohexylbenzene hydroperoxide concentrator.

    Abstract: Method for concentrating an organic hydroperoxide mixture comprising a hydrocarbon and a hydroperoxide corresponding thereto comprises evaporating a first liquid mixture in a thin- film evaporation device followed by separation in a separation zone. Both the evaporation device and the separation zone operate at a low absolute pressure at a temperature lower than the thermal degradation temperature of the hydroperoxide to prevent thermal decomposition thereof. The process is particularly useful for concentrating an oxidation product made from the oxidation of cyclohexylbenzene.

    Abstract: In a process for producing phenol and/or cyclohexanone, a cleavage reaction mixture containing cyclohexyl-1 -phenyl-hydroperoxide and cyclohexylbenzene is contacted with sulfuric acid and water under cleavage conditions effective to form a cleavage reaction effluent containing phenol, cyclohexanone, cyclohexylbenzene, water, sulfuric acid and 1-phenylcyclohexanol. At least a portion of the cleavage reaction effluent is neutralized with a basic material to produce a neutralized cleavage product and at least a portion of the neutralized cleavage product is supplied in the absence of an added dehydration catalyst to a distillation column. The distillation column is operated so that at least a portion of the neutralized cleavage product is exposed to a temperature greater than 70°C at least one location in the distillation column whereby at least a portion of the 1 -phenylcyclohexanol in the neutralized cleavage product is dehydrated to phenylcyclohexene.
