Abstract: In a process for preparing a multiplephase multimetal oxide composition comprising Mo, V, Cu and, if desired, further elements, at least one phase is preformed separately and dispersed in a plastically deformable precursor composition of a further phase. The mixture is dried and calcined. The multimetal oxide composition is suitable as active composition of catalysts for the catalytically oxidation of organic compounds in the gas phase, in particular for the oxidation of acrolein to acrylic acid.

Abstract: A novel metal injection molding material contains a) from 40 to 70% by volume of metal powder, including at least 50% by weight, based on the total amount of metal, of an iron-containing powder, at least 90% by weight, based on the amount of this iron-containing powder, of the particles of which have an effective diameter of at least 40 micrometers, b) from 30 to 60% by volume of a thermoplastic binder and c) from 0 to 5% by volume of a dispersant and/or other assistants. This injection molding material is shaped by injection molding, the injection molded parts are freed from the binder and said parts freed from the binder are sintered.

Abstract: Disclosed is a method for producing a catalyst containing vanadium, phosphorus, and oxygen, which is used for oxidizing the gas phase of a hydrocarbon having at least four carbon atoms to maleic anhydride. According to the inventive method, a corresponding catalyst precursor which contains vanadium, phosphorus, and oxygen and is provided with particles having an average diameter of at least 2 mm is converted into a catalytically active form by means of calcination, and a flow of the catalyst precursor is transported on a conveyor belt across at least one calcination area over a distance 1 n at an essentially steady speed in order to be calcinated. The variation over time of the gas temperature in relation to the set point value amounts to n /2 of the calcination area, while the local difference in the gas temperature between any positions in the area of the flow of the catalyst precursor, which is located within the second half 1 n /2 of the calcination area, amounts to
