| titleOfInvention | Process for producing a VPO catalyst |
| abstract | The disclosure relates to a process for producing a VPO catalyst containing molybdenum and a vanadyl pyrophosphate phase, which comprises the steps: a) provision of a reaction mixture comprising a V(V) compound, a P(V) compound, an Mo compound, a reducing agent and a solvent, b) reduction of the V(V) compound by means of the reducing agent at least in parts to give vanadyl hydrogenphosphate in order to obtain an intermediate suspension, c) filtration of the intermediate suspension from step b) in order to obtain an intermediate, d) drying of the intermediate at a temperature of not more than 350° C. in order to obtain a dried intermediate and e) activation of the dried intermediate at a temperature above 200° C., characterized in that not more than 0.2% by weight of water, based on the weight of the reaction mixture, is present in step a) and no water is withdrawn during the reduction in step b). The disclosure further relates to a VPO catalyst which is able to be produced by the process of the disclosure and also a catalyst containing the molybdenum-containing vanadium-phosphorus mixed oxide. |
