  • Catalyst and process for producing unsaturated aldehyde and unsaturated acid
    Patent number: 5929275
    Abstract: A catalyst for the production of unsaturated aldehyde and unsaturated acid, obtained by loading a catalytically active component on a carrier and calcining the loaded catalyst, characterized by an average particle diameter of the catalyst of 4 to 16 mm, an average particle diameter of the carrier of 3 to 12 mm, a calcining temperature of 520 to 600.degree. C. and an amount of the catalytically active component loaded on the carrier of 5 to 80% by weight ?weight of the catalytically active component)/(weight of the catalytically active component+weight of the carrier+weight of a strength improver)!, and a process for producing unsaturated aldehyde and unsaturated acid with the catalyst.
