Abstract: The invention relates to a catalyst for producing an α,β-unsaturated carboxylic acid by gas phase oxidation of an α,β-unsaturated aldehyde, comprising a moulded body support having an active material applied thereto, characterised in that the active material covering q is a maximum 0.3 mg/mm
2 , Q being the active material part of the catalyst in wt.-% and S
m being the specific geometric surface of the moulded body support in mm
2 /mg. The invention also relates to a method for producing said catalyst and to a method for producing an α,β-unsaturated carboxylic acid by gas phase oxidation of an α,β-unsaturated aldehyde on a fixed bed catalyst which contains the bulk material of the catalyst. Due to said catalyst, the over-oxidation into CO
x is reduced and the selectivity of the formation of acrylic acid is increased, whilst maintaining a continuous high yield in acroleine.

Abstract: The invention relates to a method for producing a catalytically active mass that is a mixture of a multi-element oxide containing the elements Mo and V and at least one oxide of molybdenum, wherein a spray powder P is produced by spray-drying an aqueous solution or an aqueous suspension of starting compounds containing the elements of the multi-element oxide, a powdery oxide of molybdenum and optionally shaping auxiliary agents are added to the spray powder, molded bodies are molded from the resulting mixture, and the molded bodies are converted into the catalytically active mass by thermal treatment. The catalytically active mass is used in a method for the partial gas-phase oxidation of (meth)acrolein, optionally after the catalytically active mass has been applied to a molded carrier body.
