Process for the recovery of cyclohexanone and cyclohexanol from cyclohexanone production distillation bottoms

摘要

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 (Al2O3) content of at least about 95 wt.%, and more preferably greater than about 99 wt.%.
