  • Catalyst, Method for Producing Catalyst, and Method for Producing alpha,beta-Unsaturated Aldehyde, alpha,beta-Unsaturated Carboxylic Acid and alpha,beta-Unsaturated Carboxylic Acid Ester
    Publication number: 20240017247
    Abstract: An object of the present invention is to provide a catalyst with high yields of target products such as an ?,?-unsaturated aldehyde and an ?,?-unsaturated carboxylic acid. Problems are solved by a catalyst containing at least molybdenum and having a COD (chemical oxygen demand) of the catalyst of greater than 300 ppm and less than 11,000 ppm.

  • Catalyst, Method for Producing Catalyst, and Method for Producing alpha,beta-Unsaturated Aldehydes, alpha,beta-Unsaturated Carboxylic Acids and alpha,beta-Unsaturated Carboxylic Acid Esters
    Publication number: 20240009653
    Abstract: An object of the present invention is to provide a catalyst with high selectivity for an ?,?-unsaturated aldehyde, an ?,?-unsaturated carboxylic acid, and the like. Problems are solved by a catalyst containing at least molybdenum and bismuth and having a B/A of 1.3 to 5 when a ratio of the amount of bismuth atoms to the amount of molybdenum atoms, calculated from ICP (inductively coupled plasma) atomic emission spectrometry is A, and a ratio of a peak area of bismuth atoms to a peak area of molybdenum atoms, measured by X-ray photoelectron spectrometry is B.

  • Catalyst
    Publication number: 20220387976
    Abstract: An object of the present invention is to provide a catalyst capable of improving the selectivity of unsaturated aldehydes and unsaturated carboxylic acids, and a catalyst containing molybdenum, antimony, bismuth, and iron, wherein an atom ratio of the antimony to the molybdenum on a surface of the catalyst is greater than an atom ratio of the antimony to the molybdenum in the entire catalyst is provided.
