Use of tetrahydrobenzoxazines I, wherein R 1 is a hydrocarbyl radical and R 2 , R 3 , R 4 and R 5 independently represent hydrogen atoms, hydroxyl groups or hydrocarbyl radicals and wherein R 2 to R 5 can also form a second and a third tetrahydrooxazine ring, with the proviso that at least one of the substituents has 4 to 3000 carbon atoms and the remaining substituents, when they are hydrocarbyl radicals, each have 1 to 20 carbon atoms, as stabilizers for stabilizing inanimate organic material, in particular turbine fuels, against the action of light, oxygen and heat. |
