ABSTRACT:
In the production of a Mo-Bi-Na composite oxide catalyst by the process comprising incorporating compounds as respective element sources into a composite and subjecting the composite to heat treatment, a bismuth subcarbonate in which at least a part of required Na has been solid-dissolved is used as a Bi source compound. The activity of the catalyst is significantly improved by introducing Bi and Na in the form of the specified water insoluble compound into the catalyst.
