  • Catalyst for producing unsaturated aldehyde and/or unsaturated carboxylic acid, method for producing same, and method for producing unsaturated aldehyde and/or unsaturated carboxylic acid
    Patent number: 9656248
    Abstract: Provided is a catalyst having high activity and yield of a target product for producing an unsaturated aldehyde and/or an unsaturated carboxylic acid and further having high mechanical strength. The catalyst is a catalyst prepared by a method in which a catalyst formulation satisfies specified atomic ratios; and in the preparation thereof, a molybdenum component raw material is an ammonium molybdate, a solvent for dissolving the ammonium molybdate is water, a bismuth component raw material is bismuth nitrate, and a solvent for dissolving bismuth nitrate is a nitric acid aqueous solution, and the weight of water for dissolving the ammonium molybdate, the weight of the nitric acid aqueous solution for dissolving the bismuth nitrate, and the acid concentration of the nitric acid aqueous solution are satisfied with specified ranges, respectively.
    Type: Grant

    Date of Patent: May 23, 2017
    Assignee: Nippon Kayaku Kabushiki Kaisha
    Inventors: Yuuta Nakazawa, Yoshiko Shoya, Masaki Nakahara, Eiji Nishimura, Kazuo Shiraishi, Tatsuhiko Kurakami, Ryota Hiraoka
  • Catalyst for producing unsaturated aldehyde and/or unsaturated carboxylic acid, method for producing the catalyst, and method for producing unsaturated aldehyde and/or unsaturated carboxylic acid using the catalyst
    Patent number: 9393553
    Abstract: An object of the invention is to provide a novel catalyst having high mechanical strength and capable of obtaining an unsaturated aldehyde or an unsaturated carboxylic acid in a high yield and a method for producing the same, and a method for producing an unsaturated aldehyde and/or an unsaturated carboxylic acid using the catalyst. By containing silane-treated glass fibers in a catalytic active component composed of molybdenum and bismuth as essential components, high mechanical strength is revealed, and it is possible to obtain an unsaturated aldehyde or an unsaturated carboxylic acid in a high yield.
