A process for preparing a Molybdänmischoxidvorstufe and thus available Molybdänmischoxidvorstufe

2009 
A process for preparing a Molybdanmischoxidvorstufe comprising the steps of a) preparing a first solution containing a molybdenum starting compound and at least one other metal-containing starting compound selected from a vanadium-containing and / or tellurium and / or antimony-containing and / or tungsten-containing starting compound, b) preparing a second solution containing a niobium-containing and / or iron-containing and / or bismuth and / or antimony-containing starting compound, c) the introduction of the first and the second solution into a micro-mixing reactor comprising a mixing / reaction chamber and a temperature control, the / is located in the mixing reaction chamber, wherein the first and the second solution in lying substantially opposite solution sub-streams separated in the are fed to the mixing / reaction chamber of the micro-mixing reactor and mixed there, wherein a Molybdanmischoxidvorstufe is formed, and d) of spreading the mixture obtained in step c) Molybdanmischoxidvorstufe from the mixing / reaction chamber.
