Abstract:  The empirical equation I₀= μ• [Co]₀^0.55 • [ROOH]₀^0,75 (I₀ is initial intensity of chemiluminescence) for oxidation of n -heptane initiated by the system of cumene hydroperoxide and cobalt(II) naphthenate has been found by chemiluminescence method. The kinetic orders lower than one with respect to the initial concentrations of both Co(II) naphthenate and hydroperoxide have been accounted for by association of naphthenate molecules and by formation of bicentric complexes of cobalt which precede the proper decomposition process. An attempt has been made to elucidate the elementary reaction steps leading to the catalyst deactivation.
