Abstract
Abstract The present invention relates to a catalyst composition consisting of oxide complexes of vanadium, molybdenum and germanium plus an additional oxide selected from the group consisting of iron, nickel, thallium, phosphorus, indium, bismuth and the rare earths and optionally an oxide selected from the group copper, magnesium, manganese, aluminum, titanium, potassium, rubidium, cesium, niobium, tantalum, chromium, tungsten, uranium, cobalt, silver, zinc, tin, gallium, arsenic and antimony. These catalysts are especially useful for producing acrylic acid from acrolein and for producing methacrylic acid from methacrolein.
