Abstract
Organic by-products having higher boiling points than cyclohexanone (usually obtained from the bottoms of a distillation operation to separate cyclohexanone from other reaction products during cyclohexanone production) can be converted to recoverable cyclohexanone and cyclohexanol using a catalyst having high aluminum oxide concentrations. The preferred catalyst is one which has an aluminum oxide (Al,O,) content of at least about 95 wt. %, and more preferably greater than about 99 wt. %.
