Abstract
A process is provided for the preparation of coated iron phosphorus oxide containing catalysts useful in the oxydehydrogenation of saturated carboxylic acids, wherein the catalysts are prepared by partially wetting a carrier or support in an aqueous silica solution/suspension, contacting the partially wet carrier with a powder of the iron phosphorus oxide catalyst, drying and calcining.
Claims19
