Multiple metal oxide containing material present in the pure phase I, the alkali metal Mo, and V

摘要

Multiple metal containing an element with the case of one or several selected from the group comprising the elements of the sixth main group through the third main group of the periodic table and transition elements lanthanum series and V and Mo, of the Periodic Table oxide material is disclosed. It is produced in the presence of alkali metals except Li, multimetal oxide material of the can, has a phase structure i. The use of multiple metal oxide material according to the invention as the active material in the catalyst for the partial gas phase oxidation is disclosed.
