Abstract

Official abstract text for this publication.

A process for producing phenol is described in which a feed comprising alkylbenzene hydroperoxide is contacted with a cleavage catalyst under cleavage conditions effective to convert at least part of the hydroperoxide into phenol, the process is characterized in that at least a part of the deactivated catalyst is regenerated using a oxidizing material comprising hydrogen peroxide and then return to the process. A method of regenerating the cleavage catalyst is also described.

First claim

Opening claim text (preview).

What is claimed is: 1. A process for producing phenol comprising: (a) contacting a feed comprising alkylbenzene hydroperoxide with a cleavage catalyst comprising of a zeolite having a FAU, *BEA, MTW, or MOR framework type, and/or a solid-acid comprising a sulfated transition metal oxide under non-aqueous cleavage conditions effective to convert at least part of the alkylbenzene hydroperoxide to phenol; (b) regenerating at least part of the cleavage catalyst by contacting the cat…
