A liquid concentrate comprising essentially:

Protection of liquid fuels

The use of tetrahydrobenzoxazines I where Ris a hydrocarbyl radical and R, R, Rand Rare each independently hydrogen atoms, hydroxyl groups or hydrocarbyl radicals, and where Rto Rmay 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.

Use of tetrahydrobenzoxazines as stabilisers

An additive formulation suitable for antistatic modification and improving the electrical conductivity of inanimate organic material, consisting essentially of

Use of tetrahydrobenzoxazines as stabilizers

A synergistic mixture comprising from 1 to 99.9% by weight of compounds having structural elements (I) in which the free valencies on the oxygen atom and on the nitrogen atom may be combined to form a five-, six- or seven-membered ring and the benzene ring may also bear substituents at one or more of the free positions, and from 0.1 to 99% by weight of sulfur-containing organic compounds with antioxidant action. This synergistic mixture is suitable as a stabilizer for stabilizing inanimate organic material, especially mineral oil products and fuels, against the action of light, oxygen and heat.

Use of tetrahydroberizoxazines as stabilisers

Preparation of bifunctional polyisobutenes in which isobutene or an isobutene-containing monomer mixture is polymerized in the presence of a Lewis acid and a compound of the formula I in which X is an acyl radical or the radical of an organic or inorganic acid group, Rto Rare identical or different and are hydrogen or a hydrocarbon radical.

Process for preparing polyisobutenes

An additive formulation suitable for antistatic modification and improving the electrical conductivity of inanimate organic material, consisting essentially of (A) from 1 to 50% by weight of an olefin-sulfur dioxide copolymer, (B) from 1 to 50% by weight of a compound which comprises one or more basic nitrogen atoms and has at least one relatively long-chain linear or branched hydrocarbon radical having at least four carbon atoms or an equivalent structural element which ensures the solubility of component (B) in the inanimate organic material,(C) from 0.1 to 30% by weight of an oil-soluble acid and(D) from 1 to 80% by weight of a high-boiling organic solvent which consists of one or more molecule types, where at least 80% by weight of these molecule types have a boiling point of more than 150&#xb0; C. at standard pressure,where the sum of all components adds up to 100% by weight.

The present invention relates to the use of at least one heterocyclic compound of the formula (I) in which R is H or C-C-alkylas a frictional wear-reducing additive in fuel compositions; to corresponding additized fuel compositions and their preparation; and to additive concentrates which comprise such compounds.
