This publication contains evaluated and estimated data on the kinetics of reactions involving propene and allyl radical and various small inorganic and organic species which are of importance for the proper understanding of the early stages of propene and the intermediate stages of propane and isobutane combustion and pyrolysis. It is meant to be used in conjunction with the kinetic data given in earlier publications, which is of direct pertinence to the understanding of methane, ethane, methanol, propane and isobutane pyrolysis and combustion, but which also contains a large volume of data that are applicable to the propene system. The temperature range covered is 300–2500 K and the density range 1×1016to 1×1021molecules cm−3.
