Inhibitive effect of 5-(2-hydroxybenzylidene) rhodanine in oxidation of alkylbenzenes

摘要

Antioxydant and antiradical activities of 5-[2-oxybenzylidene] rhodanine in the process of alkylbenzenes oxidation have been studied. Kinetic parameters of inhibtied oxidation have been examined. The antioxydant has been found to terminate the oxydation chains by the reaction with peroxyradicals of alkylbenzenes and also to suppress the reaction degenerated chain branching as a result of hydroperoxides decomposition by molecular mechanism. Kinetics and mechanism of interaction of 5-[2-oxybenzylidene]rhodanine with cumyl hydroperoxide have been studied 5-[2-oxybenzylidene] rhodanine could be falled in the category of oxidation inhibitors of combined action.
