Process for producing catalysts for synthesis of unsaturated aldehydes and unsaturated carboxylic acids.

摘要

Disclosed is a process for producing a multi-component catalyst containing molybdenum and bismuth and used for synthesis of unsaturated aldehydes and unsaturated carboxylic acids, characterized in that dried starting materials for the catalyst are calcinated in an atmosphere containing 1 vol% or more of a nitrogen oxide and 0.5 vol% or more of oxygen.
