Abstract The oxidation of propene at low and intermediate temperatures (580–715 K) has been studied experimentally using a static reactor. Gas chromatographic analysis was used for stable species determination. The experimental results were used to postulate the main reaction paths of the mechanism. A region of negative temperature coefficient (NTC) was determined between 625–655 K and cool flames were indicated at temperatures below this range. Changes in the product distribution indicated that a transition in the mechanism was occurring across the region of NTC, from low to intermediate temperatures. The change in the mechanism with increasing temperature was attributed in part to the change in the position of equilibrium of CH3 + O2 = CH3O2, and also to the competition between radical addition to the propene and H abstraction from the propene.
