Abstract: The invention relates to a process for producing a catalyst for gas-phase oxidations, which comprises weighing a particulate inert support having a total mass of M support into a fluidized-bed apparatus, providing an aqueous suspension of a catalytically active material or sources therefor and a binder having a binder content of B susp , fluidizing the inert support by introduction of a gas stream heated to a temperature of T gas at a flow rate of Q gas , and spraying the suspension at a rate of Q susp onto the fluidized inert support. When Q gas , Q susp , B susp , M support and T gas are selected within the ranges 3000 gas [m 3 /h] susp [g/min] susp [% by weight] support [kg] gas [° C.] K=0.020 Q gas -0.055 Q susp +7.500 B susp -0.667 M support +2.069 T gas -7 satisfies the relationship 127.5

Abstract: A process is described for producing a catalyst for gas-phase oxidations, in which a suspension of TiO2 and V2O5 particles is applied to a fluidized inert support, wherein at least 90% by volume of the V2O5 particles have a diameter of 20 mum or less and at least 95% by volume of the V2O5 particles have a diameter of 30 mum or less. The defined particle size distribution of the V2O5 allows a high coating efficiency.

Abstract: A catalyst for gas-phase oxidations which comprises an inert support and a catalytically active composition comprising transition metal oxides applied thereto, or a precatalyst, is described. The (pre)catalyst is obtained by treating the inert support with an aqueous suspension or solution of the transition metal oxides or their precursor compounds, where the suspension contains a binder dispersion and the binder is a copolymer of an alpha-olefin and a vinyl-C 2 -C 4 -carboxylate whose vinyl C 2 -C 4 -carboxylate content is at least 62 mol %.
