摘要：

The method for the synthesis of 7,7,9-trimethyl-6,7-dihydrofuro[3,2-f]quinoline was developed. The parameters characterizing its antioxidant activity, the stoichiometric inhibition factor (f a parts per thousand 3), and the rate constant of the reaction with peroxy radicals (fk (7) = 2.4 center dot 10(5) L mol(-1) s(-1), 60 A degrees C) were determined for the model system of initiated ethylbenzene oxidation. The inhibition stoichiometric factor of furodihydroquinoline is 2, but the colored product formed as a result of its conversion in oxidized hydrocarbons provides the additional inhibition with k (7) = 6.3 center dot 10(3) L mol(-1) s(-1).
