Abstract
The present invention is a process for the oxidation of olefins to unsaturated aldehydes and acids using a catalyst containing iron, bismuth, molybdenum plus at least one of nickel, cobalt, magnesium, zinc, cadmium or calcium and according to the invention, an element selected from germanium, cerium, thorium, manganese, niobium, chromium, praseodymium, yttrium, zirconium, ruthenium, gallium, tin, indium, copper, lanthanum, tantalum or tungsten. These catalysts may also contain certain elements that further enhance the desirability of the oxidation process.
