ABSTRACT:
A coated catalyst which consists of a hollow cylindrical carrier and a catalytically active oxide material applied to the outer surface of the carrier, the applied catalytically active oxide material being applied in a coat thickness of from 10 to 1000 .mu.m, and having a specific catalytic surface area of from 20 to 30 m.sup.2 /g and an abrasion of <10, preferably <5, particularly preferably <0,5, % by weight in the turntable abrasion test. The catalyst is useful in the preparation of acrylic acid by the gas phase oxidation of acroleins.
