Patent number: 8563774Abstract: Disclosed is a method for producing a catalyst, in which physical properties of a dried material or a calcined material in a production process of the catalyst are stable and a change in at least one of a catalyst activity and a selectivity to a target product is small and hence reproducibility of the catalyst is excellent. The present invention is a method for producing a catalyst containing molybdenum, bismuth, and iron, which contains the steps of washing a surface of at least one device equipped in an apparatus for the production of catalyst, to which a solid matter adheres, with a basic solution, and producing the catalyst with the apparatus for the production of catalyst thus washed.Type: GrantFiled: March 15, 2013Date of Patent: October 22, 2013Assignee: Mitsubishi Rayon Co., Ltd.Inventors: Masahide Kondo, Masanori Nitta, Hiroyuki Naitou, Toru Kuroda, Seiichi Kawato
