HCID 13229Cyclohexylbenzene

Procedure

A cyclohexylbenzene-cyclohexanone-phenol-containing mixture, for example as obtained by the cleavage of cyclohexylbenzene hydroperoxide, is separated by first catalytically hydrogenating selectively the phenol in the mixture, resulting in a mixture of cyclohexylbenzene, which is unchanged, and cyclohexanone; the thus obtained mixture is subjected to fractional distillation to obtain cyclohexylbenzene which can be returned as to a process for the production of cyclohexylbenzene hydroperoxide, and cyclohexanone.
