Kinetic description of the oxidation of hydrocarbons inhibited by sufur-containing hydrogenated quinolines

Article abstract of DOI:10.1007/BF00717333

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 deg 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 dithiothione 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. - Key words: hydrogenated quinolines, dithiothione derivatives; n-decane, n-decene, ethylbenzene, β-carotene, inhibited oxidation.
