Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress sticking of a substance derived from a catalyst to an inner surface of a vapor-phase reactor or an apparatus surface of the interior in a method for a vapor-phase oxidation reaction in which an oxide catalyst is used and a component liberated from the oxide catalyst may deposit on the inner surface of the vapor-phase reactor or apparatus surface of the interior. SOLUTION: The method for the vapor-phase oxidation reaction is characterized as follows. Catalyst particles having ≤20 μm particle diameter in the oxide catalyst account for ≤2 wt% ratio. The oxide catalyst comprises molybdenum. COPYRIGHT: (C)2006,JPO&NCIPI
