Document Type and Number:
WIPO Patent Application WO/2021/142938
Kind Code:
A1
Abstract:
Disclosed is a catalyst suitable for the continuous production of isopentenal or isopentenol. The catalyst is composed of a ceramic corrugated plate carrier and a metal oxide active layer coated on the surface of the carrier, wherein the metal oxide active layer is made up of a metal oxide formed from an active ingredient titanium and additionally at least four metal elements selected from vanadium, chromium, manganese, iron, zirconium, niobium and molybdenum. The catalyst can be used for the preparation of isopentenal or isopentenol by means of a catalyzed rearrangement reaction.
