摘要
The present invention relates to a process for preparing molybdenum- bismuth-iron-cobalt-based multielement oxide catalysts by means of hydrothermal synthesis, wherein the hydrothermal synthesis is conducted with an aqueous solution and/or an aqueous suspension of precursor compounds of the elements present in the multielement oxide catalyst to be prepared, the pH of which has been adjusted to a value between about 6 and about 8. The present invention also further relates to the multielement oxide catalysts obtainable by this process and to the use thereof in the partial gas phase oxidation of olefins and tert-butanol.
