Abstract
The inhibiting effect of dithiolthione derivatives of hydrogenated quinolines (DTT) on the oxidation of various hydrocarbons (n-decane,n-decene, ethylbenzene, β-carotene) was investigated. The inhibiting effect of the DTTs is greater at high temperatures (>100 °C) than that of the parent hydrogenated quinolines and weaker at moderate temperatures. The DTTs do not affect the decomposition of hydroperoxides. Probably, the introduction of a dithiolthione cycle to a hydroquinoline molecule decreases its reactivity toward O2 and peroxide radicals, which favors the enhancement of the antioxidative activity of the DTTs at elevated temperatures.
