The mechanism of C-C bond cleavage, which is responsible for loss of selectivty in the oxidation of propylene to acrolein, was studied in the oxidation of CD/sub 2/=CH-CH/sub 3/ on bismuth molybdate, tin/antimony mixed oxides, silica-supported molybdenum oxide and silica- or alumina-supported vanadium oxides. Of the produced ethanal (acetaldehyde), only 0-15% contained deuterium, depending on the catalyst, which suggested that the partial oxidation of propylene to acrolein and bond rupture yielding ethanal are paralled reactions via different intermediates. The mechanisms are discussed.
