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.

Abstract: Disclosed are novel cyclohexanone compositions, and 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 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.
