Abstract: Disclosed are processes for making cyclohexanone from a feed mixture comprising cyclohexylbenzene, cyclohexanone, phenol, 3-cylclohexenone and optionally 2-cyclohexenone, comprising feeding the feed mixture to a first distillation column and hydrogenating a fraction from the first distillation column in a hydrogenation reactor separate from the first distillation in the presence of a hydrogenation catalyst under hydrogenation conditions. A cyclohexanone-rich upper effluent comprising 3-cyclohexenone and 2-cyclohexenone at low concentrations can be obtained from the first distillation column.

Abstract: Disclosed are processes for making such cyclohexanone compositions from a mixture comprising phenol, cyclohexanone, and cyclohexylbenzene. Such cyclohexanone compositions comprise at least 99 wt % cyclohexanone, at most 0.15 wt % water, and at most 500 wppm combined of certain cyclohexanone impurities selected from the group consisting of: benzene, cyclohexene, pentanal, cyclopentanol, cyclohexanol, and phenol.

Abstract: Disclosed are processes for making cyclohexanone from a mixture comprising phenol, cyclohexanone, cyclohexylbenzene, and an S-containing component, comprising a step of removing at least a portion of the S-containing component to reduce poisoning of a hydrogenation catalyst used for hydrogenating phenol to cyclohexanone.

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: In a process for separating a mixture comprising cyclohexanone and phenol, a solid-phase basic material, such as basic ion-exchange resin, is used to remove acid and/or sulfur from the mixture prior to separation. The process results in reduced amount of contamination such as cyclic ethers in the cyclohexanone and/or phenol products.
