    Abstract: Fuels for spark ignition engines, which fuels contain small amounts of a polyether amine and/or polyether amine derivative of the general formula … … in which R is a phenol- or alkylphenol-polyether radical of the general formula … … or a cyclohexyl- or alkylcyclohexyl-polyether radical of the general formula … … R and R may be identical or different and are hydrogen, the phenol- or alkylphenol-polyether radical (IIIa), the cyclohexyl- or alkylcyclohexyl-polyether radical (IIIb), the acyl radical of a carboxylic acid having 2 to 24 carbon atoms or the hydroxyalkyl radical of the general formula … … or R is an alkyl radical having 1 to 20 carbon atoms and R is hydrogen, the phenol- or alkylphenol-polyether radical (IIIa), the cyclohexyl- or alkylcyclohexyl-polyether radical (IIIb), the acyl radical of a carboxylic acid having 2 to 24 carbon atoms or the hydroxyalkyl radical (IV), R is the carboxylate radical of a carboxylic acid having 2 to 24 carbon atoms, R , R and R may be identical or different and are hydrogen or a hydrocarbon radical having 1 to 30 carbon atoms, R is a polyether chain comprising alkene oxides having 2 to 8 carbon atoms or mixtures of these alkene oxides having 2 to 100 alkene oxide units in the chain, and R is hydrogen or a hydrocarbon radical having 1 to 6 carbon atoms, and m is the numbers 0 to 5, the mean molecular weight Mn of the polyether amines or polyether amine derivatives (I) or (II) being 500 to 8000, and the polyether amines or the parent polyether amines to the polyether amine derivatives being prepared by amination of phenol- or alkylphenol-polyethers of the general formula … … or of cyclohexyl- or alkylcyclohexyl-polyethers of the general formula … … in which R , R , R and R are as defined above, using ammonia or primary amines. … The novel polyether amines and their derivatives have an improved valve-cleaning action.

    Abstract: The use of tetrahydrobenzoxazines I (See formula I) where R1 is a hydrocarbyl radical and R2, R3, R4 and R5 are each independently hydrogen atoms, hydroxyl groups or hydrocarbyl radicals, and where R2 to R5 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.
