Transphase catalysts effectiveness. popup.stage_title Head Shendrik Aleksandr Nikolajevich, Registration Date 14-03-2013 Organization Donetsk National University popup.description2 It has been studied the molecular oxygen activation by methyl- and halogen-substituted hydroquinones in water medium which was accompanied with the oxygen-centered radicals formation. The kinetic parameters of this reaction were defined by the inhibitor method. The mechanism of radical generation in the hydroquinone oxidation was established. It has been shown that bianions of hydroquinone in the order of magnitude were more active than the correspond monoanions regarding to molecular oxygen in the one-electron oxidation. Observed Hammet correlation proved to similarity of oxidation mechanism of hydroquinone derivatives and allowed to estimate the constant values of electron transfer from the substitutive hydroquinones to molecular oxygen.
