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.

Process for making cyclohexanone and/or phenol

Disclosed is (i) a process of making phenol and/or cyclohexanone from cyclohexylbenzene including a step of removing methylcyclopentylbenzene from (a) the cyclohexylbenzene feed supplied to the oxidation step and/or (b) the crude phenol product (ii) a phenol composition and (iii) a cyclohexylbenzene composition that can be made using the process.

Cyclohexylbenzene composition

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.
