ABSTRACT:
Disclosed are a process for producing an unsaturated aldehyde and an unsaturated carboxylic acid which comprises subjecting propylene, isobutylene or tertiary butanol to gas phase catalytic oxidation with molecular oxygen in the presence of (i) a catalyst comprising composite oxide of the formula Mo.sub.a Bi.sub.b Fe.sub.c A.sub.d B.sub.e C.sub.f D.sub.g O.sub.x and (ii) a molybdenum oxide which in itself is substantially inert to the gas phase catalytic oxidation; a process for reusing the catalyst deteriorated due to the gas phase catalytic oxidation after mixing it with the molybdenum oxide; and a method of regenerating the deteriorated catalyst by mixing it with the molybdenum oxide.
