Abstract
The invention relates to a process for producing a metal oxide catalyst capable of producing acrylic acid, acrylonitrile or the like in one stage by catalytic oxidation reaction of propane in a high yield.The invention is characterized by using one obtained by finely ground metallic Te or metallic Sb in water or an organic solvent as a raw material for the production of an oxide catalyst made of metal elements Mo—V—Nb—Te or metal elements Mo—V—Nb—Sb. The powder of the metallic Te or metallic Sb obtained by grinding preferably has a mode size of not more than 20 μm. By using the metal oxide obtained by the invention as a catalyst, it is possible to produce acrylic acid in a high yield of 35% or more from propane by a one-stage oxidation reaction.
