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

Claim (Index 11):
An additive composition comprising:\n i) a tetrahydrobenzoxazine of formula I: wherein R 1  is a 2-aminoethyl-, a N-(2\u2032-aminoethyl-)-2-aminoethyl-, a N\u2032-(2\u2033-aminoethyl-)-N-(2\u2032-aminoethyl-)-2-aminoethyl-, a N\u2033-(2\u2033\u2032-aminoethyl-)-N\u2032-(2\u2033-aminoethyl-)-N-(2\u2032-aminoethyl-)-2-aminoethyl-, or a 3-dimethylaminopropyl-radical, and R 2 , R 3 , R 4  and R 5  are each independently a hydrogen atom, a hydroxyl group or a hydrocarbyl radical having from 1 to 3000 carbon atoms which may optionally be interrupted by one or more selected from the group consisting of O, S and NR 6  moieties, wherein R 4  may optionally be a radical of formula Y wherein R 1 , R 2 , R 3  and R 5  are each as defined above and X is a hydrocarbon bridging element which consists of one or more isobutene units or comprises one or more isobutene units, or wherein R 4  may optionally be a radical of the formula Z or Z\u2032 wherein R 1 , R 2 , R 3  and R 5  are each as defined above and R 10  and R 11  are each independently hydrogen or a C 1 - to C 10 -alkyl radical, and wherein R 2  and R 3  or R 3  and R 4  or R 4  and R 5 , together with the part-structure \u2014O\u2014CH 2 NR 7 \u2014CH 2 \u2014 attached to the benzene ring, may optionally form a second tetrahydrooxazine ring, or R 2  and R 3  and R 4  and R 5 , together with the part-structures \u2014O\u2014CH 2 NR 7 \u2014CH 2 \u2014 and \u2014O\u2014CH 2 NR 8 \u2014CH 2 \u2014 attached to the benzene ring, may optionally form a second and a third tetrahydrooxazine ring, wherein R 7  and R 8  are each independently a hydrocarbyl radical having from 1 to 3000 carbon atoms and are interrupted by one or more heteroatoms selected from the group consisting of O, S and NR 6  moieties, with the provisio that at least one of R 2 , R 3 , R 4 , or R 5  is a polyisobutenyl radical having a number-average molecular weight M n  of from 200 to 40,000; and ii) at least one compound selected from the group consisting of (A) compounds which derive from succinic anhydride and have long-chain hydrocarbon radicals having generally from 15 to 700 carbon atoms, (B) polyalkenylthiophosphonate esters, and (C) Mannich adducts.
