The inhibited oxidation of ethylbenzene has been investigated in the presence of 2,6-di-tert-butyl-4-methyl-phenol (ionol). 1-Phenylethyl-hydroperoxide was used as a source of radicals. The time dependence of oxygen consumption was measured at t equals 120 degree C and simulated using a reaction mechanism consisting of 20 elementary steps. Simulation was carried out by changing the value of the rate constant of the reaction. Since the calculated curves are - at a constant rate of initiation - essentially influenced by the value of k//5, simulation is a proper method for its determination. The best fit was achieved at k//5 equals 5 multiplied by (times) 10**51 multiplied by (times) mol** minus **1 s** minus **1. The contribution of the various elementary steps to oxygen consumption has also been determined.
