Abstract
A process for preparing cresols from di-hydrocarbyl-substituted cresols, wherein the hydrocarbyl groups contain from 3 to 7 carbon atoms, is disclosed. In the process the di-hydrocarbyl-substituted cresol is contacted with a catalyst (e.g. alumina) in the liquid phase at elevated temperatures and pressure. 4,6-di-t-butyl-m-cresol is a typical feedstock.
