Abstract:
1. A catalyst for the oxidation of an olefin to an unsaturated aldehyde comprising a mixed metal oxide having the formula: wherein a is in the range from 0.1 to 1.5, b is in the range from 0 to 9, c is in the range from 0.2 to 5.0, g is in the range from 0.1 to 1.5, M is one or more selected from the group consisting of calcium, strontium, lithium, sodium, selenium, cobalt, nickel, magnesium, zinc, potassium, rubidium, thallium, manganese, barium, chromium, tin, lead, cadmium and copper, m is in the range from 0 to 9, x is determined by the valences of the other components and wherein the relative amount ratio of c to g is from 3.3 to 5.0, the relative amount ratio of c to a is from 2.0 to 6.0 and the relative amount ratio of (3a+3c+g+Σv n m n )/(2×12+2b) is from 0.95 to 1.10 with v being valence of each M, and n being the total number of M.
