An initial‐rate study was conducted to determine the kinetics of the oxidation of acrolein over a bismuth molybdate catalyst. The results were combined with results from a previous initial‐rate study of propylene oxidation on the same catalyst to develop a quantitative description of the reaction network for propylene oxidation. The redox steady‐state model with half‐order in oxygen which provided the best fit to the propylene oxidation data also provided the best fit to the acrolein oxidation data. The disappearance of propylene occurs through parallel reactions to acrolein, carbon oxides, and acetaldehyde, with subsequent oxidation of the acrolein to carbon oxides.
