ABSTRACT:
An ammoxidation catalyst comprising a molybdenum (component (1)), bismuth (component (2)), at least one element selected from the group consisting of nickel, cobalt, zinc, magnesium, manganese and copper (component (3)) and at least one element selected from the group consisting of lanthanum, cerium, praseodymium and neodymium (component (4)), over which an organic compound is subject to ammoxidation which is a composite oxide fluid bed catalyst, is prepared by i) preparing a first solution that comprises at least a portion of component (1), at least a portion of component (2), and at least a portion of component (3) but none of component (4); ii) preparing a second solution by adding a solution of component (4) to the first solution; and iii) drying the second solution obtained and calcining the solid matter obtained from the drying step.
