摘要:
In a process for the preparation of catalytically active poly-metal oxide materials containing Mo and V, a catalyst intermediate is calcined at from 300.degree. to 450.degree. C. in a gas atmosphere which, in addition to inert gases and/or steam, consists of from 0.5 to 4% by volume of O.sub.2 and, averaged over the calcination time, from 1 to 8% by volume of NH.sub.3.
