Abstract

PURPOSE: To prepare the title compound in high yield and selectivity, by the gas phase reaction of an unsaturated aldehyde with O2 in the presence of a novel catalyst having excellent catalytic activity and high resistance to the lowering of the activity by contaminants, containing a particular component such as Ga, B, etc.
CONSTITUTION: A mixture of the formula (A is K, Rb, Cs, etc.; B is Ga, B, Zn, Te, or Th; C is V or Cr; a-g are the number of each atom; when d is 12, a-f are 0.05W12, and g is the number of 0 atoms satisfying the valences of the other elements) is prepared by evaporation to dryness, etc., and baked pref. at 300W 550°C for several to several ten hours. An unsaturated carboxylic acid is prepared by contacting an unsaturated aldehyde such as acrolein, methacrolein, etc., and O2 (industrially, air) with the catalsyt prepared above, pref. at 300W450°C for 0.5- 15 sec.
