Abstract
A process for preparing epsilon-caprolactone comprising feeding benzaldehyde to an oxidation zone containing cyclohexanone, oxidizing the mixture in liquid phase in said oxidation zone in the presence of molecular oxygen, recovering epsilon-caprolactone and benzoic acid from the oxidation zone, convert the benzoic acid to cyclohexanone, and recycle the oleohexanone thus produced to the oxidation zone.
