Verfahren zur Herstellung von monolithischen Oxidationskatalysatoren und deren Verwendung bei der Gasphasenoxidation von Kohlenwasserstoffen

摘要

The invention relates to a method of producing monolithic substrate catalysts and to their use in the gas phase oxidation of carbohydrates. Said catalysts are obtained by coating the catalyst substrate with a suspension that consists of a catalytically active compound and one or more surfactants of the general formula RnYmX. R represents the hydrophobic part of the surfactant, with n being 1, 2 or 3. Y represents the hydrophilic part of the surfactant, with m being 0, 1, 2 or 3 and X represents the hydrophilic head group of the surfactant.
