| abstract |
The invention relates to a method for producing a catalyst suitable for the gas phase oxidation of organic compounds to alpha, beta-unsaturated aldehydes and / or carboxylic acids with an active phase from a multimetal oxide mass, in which a particulate catalyst precursor is produced, the oxides and / or in oxides converting compounds of the elements other than oxygen, which constitute the multimetal oxide mass, and converting them into a catalytically active form by calcination, a stream of the particulate catalyst precursor being passed through at least one constant temperature calcination zone for calcination at a substantially constant rate. |
