  • Cyclohexanone compositions and processes for making such compositions
    Patent number: 10570079
    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.
