Abstract
Catalysts having improved attrition resistance are produced by incorporating a substantially uniform appearing coating of completely calcined, catalytically active oxide material onto an inert porous support containing sorbed aqueous silica sol. Such catalysts are useful in the gas phase oxidation of unsaturated aldehydes to unsaturated acids, especially acrolein to acrylic acid.
