摘要：
The invention relates to a method for producing a catalyst, comprising an active phase, composed of a multi metal oxide and which is suitable for the gas-phase oxidation of organic compounds producing α,β unsaturated aldehydes and/or carboxylic acids. According to the invention, a particle shaped catalyst precursor is produced which contains oxides and/or compounds which can be transformed into oxides containing elements constituting the multi metal oxide mass which are different from oxygen. Said catalyst precursor can be transformed into a catalytically active form by means of calcination, whereby a flow of the particle shaped catalyst precursor for calcification is guided at a substantially constant speed through at least one calcification zone at a constant temperature.
